Answer:

94°, 120°, 152°

Step-by-step explanation:

78°=(b+36°)/2 ⇒ b/2=78°-18° ⇒ b/2=60° ⇒ b=120°
87°=(120°+x)/2 ⇒ x/2=86°-60° ⇒ x= 52°
c=360°-(120°+52°+36°)= 152°
a=(152°+36°)/2=94°

- $\frac{1}{9}$

multiply the numerators and multiply the denominators

- $\frac{2}{3}$ × $\frac{1}{6}$

= $\frac{-2(1)}{3(6)}$ = - $\frac{2}{18}$ = - $\frac{1}{9}$

Perimeter of rectangle = all sides added
= 3+3+7+7 =20

volume of sphere = 4/3 x π x r(cubed)
= 4/3 x π X 4(cubed)
= 268.08257

area of triangle = base x height / 2
= 5 x 6 / 2
=30/2 =15

volume of pyramid = base height x base width x height / 3
= 300

side of triangle ---> use Pythagoras theorem so a(squared) + b (squared) = c(squared)
4(squared) + 3(squared) = c(squared)
16 + 9 = c(squared)
25 = c(squared)
c = 5
