Answer:
x
Step-by-step explanation:
Two factors of -5 are -5 and 1. -5 and 1 make a sum of -4, so the equation can be factored into (x-5)(x+1)=0
x-5=0 or x+1=0
x=5 or x=-1
Answer:
Step-by-step explanation:
1). By definition of an exterior angle of a triangle,
Measure of exterior angle of a triangle is equal to the sum of opposite two interior angles.
From the figure attached,
m∠4 = m∠1 + m∠2
2). Property of a triangle states that " sum of interior angles of a triangle is 180°"
Therefore, m∠1 + m∠2 + m∠3 = 180°
Answer:
37.5
Step-by-step explanation:
split in the middle, 5×5=25/2=12.5
12.5= triangle
5×5=25
25=square
12.5+25=37.5
