Given: angle 2 and angle 3 form a linear pair, angle 1 and angle 3 are vertical angles, and m angle 1, m angle 4, and m angle 5
form a straight angle. Prove: m angle 2 = m angle 4 + m angle 5
1 answer:
Answer:
Step-by-step explanation:
<1 + <2 = 180 degrees (straight angle)
<3 + <5 + <4 = 180 degrees (straight angle)
<1 = <3 (vertical angles)
<1+<2 = <3+<4+<5 (straight angles)
<2 = (<3-<1)+<4+<5 (<3 - <1 = 0)
<2 = <4 + <5

I think u would do 3.5x 3 to find the area of that triangle
Answer:
a = -5
Step-by-step explanation:
(5 - 3)/(5 - a)
2/(5 - a)
perpendicular of 2/(5 - a) = -(5 - a)/2
(a - 0)/(1 - 0) = -(5 - a)/2
a/1 = -(5 - a)/2
2a = -5 + a
a = -5
Answer:
7%
Step-by-step explanation:
The percentage increase is found as ...
increase/original × 100%
= (33170 -31000)/31000 × 100%
= 2170/31000 × 100% = 7%
Sarah's increase would be 7%.
