Answer:
The answer is 55.
Step-by-step explanation:
1. angle ADB and BDC = 180.
180-80= 100 (angle BDC is 100)
because a triangle is 180 degrees, you can figure out CBD...
2. BDC + DCB is the same as
100+25=125
3. 180-125=55
The measure of R =
<h2>A . 32°</h2>
We say this because ∆PQR is an isosceles triangle whose two sides are equal . We all know that the base angles of an isosceles triangle are equal . Since ∠P and ∠R are the base angles of an isosceles triangle - ∆PQR their measure will be equal . So , the measure of ∠R = 32° .
Answer:
2x - y = 8
Step-by-step explanation:
2x - y = 8 does not belong with the other equations because C. the equation is in standard form
