Answer:
D) 67.4°
Step-by-step explanation:
by observation, and noting that triangle PQR is a right triangle
sin R = opposite length / hypotenuse
in our case, the hypotenuse is PR = 13 and the length opposite form R is QP = 12
hence
sin R = opposite length / hypotenuse
sin R = 12/13
R = sin⁻¹ (12/13) = 67.4⁰
I just wrote: 1m-9% (of the time) and 1m-0.09 (multiplied by the time). This makes sense because 9% and 0.09 are equal, just one of them is in decimal form.
Answer:
b=√119
Step-by-step explanation:
a2+b2=c2
(5×5)+(b2) =(12×12)
25+b2=144
b2=144-25
b2= 119
b=√119
Answer:
15
Step-by-step explanation:
