Answer:
y = 90°
Step-by-step explanation:
The left side base angle of the triangle and the angle of 110° form a straight angle and are supplementary, thus
base angle = 180° - 110° = 70°
The right base angle is also 70° , thus the triangle is isosceles
The line segment from the vertex is a perpendicular bisector, hence
y = 90°
Y= 3.11x+ 17.59
I got this equation by doing 23.81-20.70 to find m, which is 3.11.
Then to find b, or y-intercept, I subtracted 3.11 from 20.70 to get the origin all price and got 17.59
Answer 64
Step by step exploration
3*4*4+4*4=48+16=64
The elapsed time is 2 hours and 45 minutes.You subtract the 8 from the 10, leaving 2 hours.You subtract the 10 from the 55, leaving 45 minutes.
