Answer:
r=16c
Step-by-step explanation
20-4=r
16=r
True
Step-by-step explanation:
11.5
shown below.
v = 150 since 180 - 30
for w we need 2y and x. the base angles of the triangle are 30 and 50 therefore x = 100. 2y = 30 because corresponding angles. ergo, w = 50
x = 100
y = 15
z = 50
he needs 12.50 left
Step-by-step explanation:$62.50-$50
