1 answer:

5 0

Find the area of each face of the figure. So, find the area of one of the triangular faces and multiply it by 2 because there are 2 of them. Then find the area of the front rectangle, the back rectangle, and the bottom rectangle. Add all of these areas up to get the surface area.

Jonas has been saving for a video game . last year it costs $28 this year it costs $36 find the percent of change in the cost .

iren2701 [21]

Answer:

Last year the cost was $28.

This year the cost is $36.

$36 - $28 = $8

Percent of increase = amount of increase ÷ original amount

$8/$28 = $0.286

$0.286 · 100 = 28.6%

There has been a 28.6% of change in the cost.

Find the value of x?

Deffense [45]

Answer:

145°

Step-by-step explanation:

See the attachment. Angles A, B, and C all belong to the triangle.

We know that A + B + C = 180° since the angles of a triangle always add to 180°. We also know that when two lines meet that their sum is also equal to 180°. So we can write for each interior angle the following:

Result

<A = (180 - 88) 72

<B = (180-x) 180-x

<C = (180 - 127) 53

The sum of angles A, B, and C is equal to 180:

72 + (180-x) + 53 = 180
