h = 5

Answer:

A = 19.1°

B = 95.5°

C = 65.4°

Step-by-step explanation:

B = 5A

C = 4A-11

We know that a triangle has a total of 180° so:

180 = A + B + C

Which can be written as:

180 = A + (5A) + (4A - 11)

180 = 10A - 11

10A = 191

A = 19.1°

With A, we can work out B and C:

B = 5(19.1)

B = 95.5°

C = 4(19.1) - 11

C = 76.4 - 11

C = 65.4°

Answer:

[tex] \boxed{\sf d. \ \frac{a}{b} = \frac{10}{7}} [/tex]

Step-by-step explanation:

[tex] \sf \implies \dfrac{a - b}{b} = \dfrac{3}{7} \\ \\ \sf \implies \frac{a}{b} - \frac{b}{b} = \frac{3}{7} \\ \\ \sf \implies \frac{a}{b} - 1 = \frac{3}{7} \\ \\ \sf \implies \frac{a}{b} - 1 + 1 = \frac{3}{7} + 1 \\ \\ \sf \implies \frac{a}{b} = \frac{3}{7} + 1 \\ \\ \sf \implies \frac{a}{b} = \frac{3}{7} + \frac{7}{7} \\ \\ \sf \implies \frac{a}{b} = \frac{3 + 7}{7} \\ \\ \sf \implies \frac{a}{b} = \frac{10}{7} [/tex]

Answer:

[tex]\displaystyle \frac{3}{4}[/tex]

Step-by-step explanation:

Each mark represents [tex]\displaystyle \frac{1}{4},[/tex]therefore you have this:

[tex]\displaystyle -1\frac{1}{4} + 2 \hookrightarrow -1\frac{1}{4} + 1\frac{4}{4} \\ \\ \boxed{\frac{3}{4}}[/tex]

I am joyous to assist you at any time.

Answer:

[tex]48.5cm^{2}[/tex]

Step-by-step explanation:

This shape is actually just a rectangle with a missing triangle. We can first find the area of the rectangle with [tex]7*8=56[/tex] and subtract the triangle.

Area of missing triangle = [tex]\frac{1}{2} *b*h[/tex] (b is the base and h is the height)

Base = [tex]8-3=5[/tex]

Height = [tex]7-4=3[/tex]

Area of missing triangle = [tex]\frac{1}{2} *5*3=7.5[/tex]

Area of the figure: [tex]56-7.5=48.5[/tex]

--------------------------------------------------------------------------

Alternatively, you can find the area of each individual shape and add them all up.

Area of the rectangle: [tex]8*4=32[/tex]

Area of square: [tex](7-4)*3=9[/tex]

Area of triangle: [tex]\frac{1}{2} *(8-3)*(7-4)=\frac{1}{2} *5*3=7.5[/tex]

Total Area: [tex]32+9+7.5=48.5[/tex]

Answer:

49.2

Step-by-step explanation:

I first found the area (length x Width) of the rectangle which is 8x4= 32

Then I subtracted 7cm and 4cm to find the width of the square which is 3cm

To find the area of the square multiple 3x3= 9

Then to find the area of the triangle I subtracted 8cm and 3cm to get the length of the triangle which is 5cm

You already know the width of the triangle (3cm) so you multiply 5cm x 3cm to get 15, but snice its a triangle you’re going to divide 15 by 2 = 7.2

Lastly your going to add up all those numbers :

32+9+7.2 = 49.2

So the area of the triangle is 49.2

Answer:70

Step-by-step explanation:

Answer:

∠K =24

∠L =66

Step-by-step explanation:

first you need to find X in order to solve.

since they are Complementary they add together to equal 90 degrees

so we can set them equal to 90

13x-1=90

13x=91

x=7

now we can plug them in!

---

∠K = 3(7)+3 = 24

∠L =10(7)-4=66

Step-by-step explanation:

Hope i helped :)

Answer:

it is b

Step-by-step explanation:

it was worth the work to help you

Hey there! I'm happy to help!

Let's flip the equation so x is on the left. We want to isolate x to see what it equals.

4x+3=-13

We subtract 3 from both sides.

4x=-16

We divide both sides by 4.

x=-4.

Have a wonderful day! :D

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = - 4}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ - 13 = 4x + 3}[/tex]

Swap the sides of the equation

[tex] \longrightarrow{ \sf{4x + 3 = - 13}}[/tex]

Move 3 to right hand side and change it's sign

[tex] \longrightarrow{ \sf{4x = - 13 - 3}}[/tex]

The negative integers are always added but posses the negative ( - ) sign

[tex] \longrightarrow{ \sf{4x = - 16}}[/tex]

Divide both sides by 4

[tex] \longrightarrow{ \sf{ \frac{4x}{4} = \frac{ - 16}{4}}} [/tex]

Calculate

[tex] \longrightarrow{ \sf{x = - 4}}[/tex]

Hope I helped!

Answer:

The slope of a line characterizes the direction of a line.

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. also You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

Answer:

-3

Step-by-step explanation:

dividing a positive and a negative equals a negative so put the 4.5 in parentheses with the 1.5 and put the negative outside the parentheses. then do what's in the parentheses and add your negative which makes you get a -3
