Sum of interior angles of triangle = 180

x + x + 6 + 3x - 16 = 180

5x - 10 = 180

5x = 190

x = 38

<M = 3(38) - 16

<M = 114 - 16

<M = 98°

Solve the equation. Then check your solution. 5 /9 d = 9 /10 a. 31 / 90 c. 1/2 b. 1 31 /90 d. 50 /81

miskamm [114]

Answer:

d in (-oo:+oo)

(5/9)*d = 9/10 // - 9/10

(5/9)*d-(9/10) = 0

(5/9)*d-9/10 = 0

5/9*d-9/10 = 0 // + 9/10

5/9*d = 9/10 // : 5/9

d = 9/10/5/9

d = 81/50

What is the total surface area of the drawing?

Soloha48 [4]

Total surface area equals area of 5 rectangular faces + 2 pentagonal faces

Area of 5 rectangular faces

$=5 \times 6 \times 9 km^2$

$=270 km^2$

Area of 2 pentagonal faces can be found by drawing 5 isosceles triangles with height as shown in the diagram and multiply the result by 2.

$=5 \times \frac{1}{2} \times 9 \times 6.2 \times 2km^2$

$=279km^2$

The toatal surface area is

$=270+279=549 km^2$

The correct answer is A
