Answer: 33.85 mm
Step-by-step explanation:
Use trigonometry, tan equation
You are give the tan angle and adjacent side, you need to find the opposite side so
O
T A
Tan(72)= x/11
x= tan(72) x 11
x= 33.85
Answer:
A, $1.08
Step-by-step explanation:
1.20 / 90 = 1.08
use a calculator
It is suppose to be letter d
Answer:
Correct option is
B
90
∘
,90
∘
,90
∘
Let AB and CD be two lines Intersecting at O, such that, ∠AOD=90
∘
Now, ∠AOD=∠COB=90
∘
(Vertically opposite angles)
⟹∠AOD+∠DOB=180
o
(Angles on a straight line)
⟹90+∠DOB=180
o
∠DOB=90
∘
∠DOB=∠AOC=90
∘
(Vertically opposite angles)
Thus, all angles are 90
