Answer:
95°
Step-by-step explanation:
Angle 1 and 4 are opposite angles, thus equal, so:
3x+10 = 4x-15 =>
x = 25
Angle 1 and 4 are 85°
Angle 4 and angle 6 are called allied (or co-interior) angles, which are supplementary, i.e., angle 6 = 180 - angle 4, so angle 6 = 95°.
Angle 6 and 7 are again opposite, so angle 7 is 95° as well!
Answer:
170°
Step-by-step explanation:
We can already see that measure ∠AD is equal to 85
A square has two halves, so this square will be added.
We will have to add 85 + 85 which equals 170°
The trinomial that results from foiling the binomials is 6x^2+41x+30.
