Answer:
The measure of angle BAC is 20°
Step-by-step explanation:
step 1
Find the measure of arc BC
we have that
m∠BOC=arc BC ------> by central angle
we have
m∠BOC=40°
therefore
arc BC=40°
step 2
Find the measure of angle BAC
we know that
The inscribed angle is half that of the arc it comprises
so
m∠BAC=(1/2)[arc BC]
we have
arc BC=40°
substitute
m∠BAC=(1/2)[40°]
=20°
Answer:
Step-by-step explanation:
The given line passes through points (−3, 2) and (2, 1).
We use the formula 
to find the slope of this line.
We use the point slope formula:
We expand to get:
The slope intercept form of the line is:
Answer:
60°
Step-by-step explanation:
360 - ( 80+115+10) = 60°
Y=-3/2x + 2 this is because of algebra
Answer:
x = 71
Step-by-step explanation:
x + 25 = 96
=> x = 96 - 25
=> x = 71
