540°
Step-by-step explanation:
formula: n-2(180
n= number of sides
Answer:
20 in
Step-by-step explanation:
The formula for the volume of a triangular pyramid is V=1/3 x B x H, in which B is the area of the base and H is the height. You're given the volume and area of the base so you can just plug that into the formula. You will get 120 = 1/3 x 18 x H. You can multiply the 1/3 and 18 so you will get 120 = 6H. In this case, you are solving for H so you need to isolate the variable. You can do this by dividing both sides by 6. You will end up eith 20 = H.
True. A relation just pairs two sets. An object in the first set can relate to more than one in the second.

Answer:
see explanation
Step-by-step explanation:
∠ PQS + ∠SQR = ∠ PQR , substitute values
13x + 4 + 10x - 1 = 141 , that is
23x + 3 = 141 (subtract 3 from both sides )
23x = 138 ( divide both sides by 23 )
x = 6
Thus
∠ PQS = 13x + 4 = 13(6) + 4 = 78 + 4 = 82°
∠ SQR = 10x - 1 = 10(6) - 1 = 60 - 1 = 59°
