Answer 1

Answer:

e=7.5

Step-by-step explanation:

15=e/0.5

We simplify the equation to the form, which is simple to understand

15=e/0.5

We move all terms containing e to the left and all other terms to the right.

-2e=-15

We simplify left and right side of the equation.

-2e=-15

We divide both sides of the equation by -02 to get e.

e=7.5

Answers

They look congruent to me

Answer:

  Maybe congruent

Step-by-step explanation:

You have two isosceles triangles, one with a marked base angle of 49° and the other marked with an a.pex angle of 82°. One side of one triangle is marked as 11 cm.

Congruence

In order for the triangles to be congruent, corresponding angles must be congruent, and corresponding sides must be congruent.

Angles

Each isosceles triangle has two congruent base angles and an a.pex angle that total 180°. The base angles in the triangle on the right are ...

  2x +82° = 180°

  2x = 98°

  x = 49° . . . . . . congruent with the base angles of the other triangle

Corresponding angles of the triangles are congruent, so the triangles are similar.

Sides

Only one side in the diagram is marked, so we cannot make any claim regarding the measures of corresponding sides in the two triangles. If corresponding sides are congruent in the similar triangles, then the triangles will be congruent.

We can only conclude that the triangles may be congruent.

Answer:

155α+81

Step-by-step explanation:

There are two rectangles:

1

area₁ =- (15α+8)(7) = 15α*7 + 8*7 = 105α+56

2

area₂ = (10α+5)(12-7) = (10α+5)(5) = 10α*5 + 5*5 = 50a + 25

Total area = area₁ + area₂

Total area = (105α+56)+(50α+25)

Total area = 105α + 50α + 56 + 25

Total area = 155α + 81

If you multiply by the first law you can divide it to the power of 10 and multiply by 5
