Step-by-step explanation:
Given
s = 
( multiply both sides by a to clear the fraction )
sa = w
Answer:
y = 5.18
Step-by-step explanation:
replace x in the equation with 3.5
y = -0.72x + 7.7
y = -0.72(3.5) + 7.7
y = -2.52 + 7.7
y = 5.18
(8x + 2y) - (7x + 2y) = 30 - 24
X = 6
Answer:
Statement: ∠XYZ = ∠ABC Reasons: Below
Step-by-step explanation:
For two angles to be complementary means that the sum of the two angles is equivalent to 90°. When an angle has one of those little squares, that means the angle is a right angle, or a 90° angle. Also, since it's given that line segment AB and line segment BC are perpendicular, this means the two lines/line segments cross each other at a right angle, which also proves that line segment AB and BC have a 90° angle.
