Calculate the value of the exterior angle

Mathematics
1 answer:
marishachu [46]3 years ago
6 0

An exterior angle of the triangle equals to the sum opposite interior angles, so

8x+15 = (4x+5) + (3x+20)

8x +15 = 7x +25

x=10

Now, we can calculate the exterior angle.

8x+15 = 8*10 + 15 = 80+15 = 95

Answer is 95⁰.

What is the measure of an angle if it is 260 degrees less than six times its own complement?
poizon [28]

Answer:

40 degrees

Step-by-step explanation:

Complementary angles have a sum of 90.

y = 90 - x

The angle is 260 degrees less than six times its complement.

y = 6x - 260

90 - x = 6x - 260

350 - x = 6x

350 = 7x

50 = x

This is the measure of the complement.

y = 90 - x

y = 90 - 50

y = 40

This is the measure of the first angle.

What is the volume of a right trianular prism with the dimesions of 15 11 17
Harlamova29_29 [7]

Answer:

1402.5 Cubic Units

Step-by-step explanation:

Volume of a Triangular Prism: V = \frac{1}{2}bhl

b - base

h - height

l - length  

15 is the height, 17 is the length, and 11 is the width  (assuming which is the base).

V=0.5 * (11 * 15 * 17) \\V=0.5*2085\\V=1402.5

The volume of the prism should be 1402.5 cubic units.
