Step-by-step explanation:
For the triangle on the bottom right the missing angle is
180- (74+50)= 56°
For the triangle on the bottom left the missing angle is
180- (45+80)= 55°
For the triangle in the middle the missing angle is
180- (54+51)= 75°
For the triangle on top the missing angle is
180- (80+54)= 46°
180- (74+51)= 55°
180- (46+55)= 79°
Volume = (1/3) * π * r² * h.
= (1/3) * π * 3² * 4.5.
= (1/3) * 127.23450247
= 42.41115 cm^3
-3 + 7x = -12
First, simplify -3x + 7x to get 4x. / Your problem should look like: 4x = -12
Second, divide both sides by 4. / Your problem should look like: x =
Third, simplify

to 3. / Your problem should look like: x = -3
Answer:
x = -3
Is there picture where the x is?
perimeter is the length of the sides. not enough info
