Answer:
17, 10
Step-by-step explanation:
3x - 9 = 42 (opposite sides have same length)
3x = 51
x = 17
4y - 3 = 37
4y = 40
y = 10
Answer:
m∠ABC = m∠EDC = 154°
Step-by-step explanation:
The roof forms and isosceles triangle and the following relationships can be observed:
m∠EDC + m∠ABC = 52 = 180
m∠ABC = m∠EDC = 64.
Since the frame of the walls make a 90 degree angle with the roof, then:
m∠CDB + 90 = m∠EDC
m∠CBD + 90 = m∠ABC
m∠ABC = m∠EDC = 64 + 90
m∠ABC = m∠EDC = 154°
Answer:
Amy-24
Barry-21
Clarence-17
Step-by-step explanation:
Clarence is the youngest and so you add 4 to that to get Barry, add 3 more to that to get Amy.
