(8). (2,1)
Given:
Vertical angles.
One angle is 85°.
To find:
The measure of ∠1, ∠2 and ∠3.
Solution:
∠2 and 85° are vertically opposite angles and ∠1 and ∠3 are vertically opposite angles.
Vertical angle theorem:
If two lines are intersecting, then the vertically opposite angles are congruent.
⇒ m∠2 = 85°
Sum of the adjacent angles in a straight line = 180°
m∠2 + m∠3 = 180°
85° + m∠3 = 180°
Subtract 85° from both sides.
85° + m∠3 - 85° = 180° - 85°
m∠3 = 95°
By vertical angle theorem:
⇒ m∠1 = m∠3
⇒ m∠1 = 95°
Therefore m∠1 = 95°, m∠2 = 85° and m∠3 = 95°.
Answer:
The answer is D
Step-by-step explanation:
D
Answer:
first you would find the sum of all the people who DONT have grey hair (15)
5:15 or if simplified it would be 1:3 pls mark brainliest if correct :D
10/1 = 43.5/x
cross multiply
10x=43.5
divide by 10 on each side
x = 4.35
it will take 4.35 minutes
