2. Michael made 10 pies. He cut each pie into 8 pieces. How many pieces of pie?

Work out the unknown angles. Give reasons for each answer.

zalisa [80]

A)

Because the sum of angles in a triangle must equal 180° we can say:

62+α+90=180

α+152=180

α=28°

b)

Since all sides have equal length, all angles must have equal measure. (This is an equilateral triangle). And again, because the sum of the angle must be 180° we can say:

b+b+b=180

3b=180

b=60°

PLEASE HELP ME WITH THIS QUESTION

alekssr [168]

Answer:

The second option, 1,008 cm²

Step-by-step explanation:

This shape has 5 sides to solve for with reguards to surface area.

Let us solve for them all.

[1 & 2 - the triangles]

12 * 9 = 108 cm²

-> I am not going to divide since we have 2 congruent triangles

[3 - the bottom side]

25 * 12 = 300 cm²

[4 - the side facing away]

25 * 9 = 225 cm²

[5 - the side facing up]

25 * 15 = 375 cm²

Now we will add them together for the total.

108 + 300 + 225 + 375 = 1,008 cm²

The surface area for the triangular prism shown is 1,008 cm².
