Hello from MrBillDoesMath!
Answer:
t = 135 is on example
Discussion:
Consider t = 135 (degrees)
sin(t) = + Sqrt (2)/2
cos(t) = - Sqrt(2)/2
tan(t) = -1
Visualization: 135 is in second quadrant where sin ("y component') is positive and cos ("x component") is negative. This implies that ratio ( or tan(t) ) is also negative.
Thank you,
MrB

Use Pythagorean theorem.
15^2+20^2=c^2
225+400=c^2
√655=c
c=25
Answer: D.) 25 m
Answer:
15.75
Step-by-step explanation:
A = (B + b)×h/2
= (4 + 5)×3.5/2
= 9×3.5/2
= 4.5×3.5
= 15.75
