Step-by-step explanation:
Use tan relation :
tan85.7=h/80
h=tan85.7×80
h=1063.96ft
Answer:
1:C
2:B
3:7 across 10 down
2 across 9 down
Step-by-step explanation:
Angle A = angle U since they're both right angles (both 90 degrees). This is what the square marker means.
segment AC = segment UW
Angle C = angle W because they have the same angle marker
---------------------
we have two pairs of congruent angles, with segments between them that are congruent. So we use the ASA property
The final answer is choice E.
Answer:
50.265
Step-by-step explanation:
Answer:
x = 13.5 and y = 7
Step-by-step explanation:
Given equations are :
x + y = 20.5 ...(1)
x − y = 6.5 ...(2)
Add equation (1) and (2).
x + y + x- y = 20.5+6.5
2x = 27
x = 13.5
Put the value of x in equation (1).
13.5 + y = 20.5
y = 20.5-13.5
y = 7
Hence, the values of x and y are 13.5 and 7.
