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°
Let, the numbers = x,y
x/y = 3/5
total ratio units = 3+5 = 8
value of 1 unit = 135/8 = 16.875
So, numbers would be 3(16.875) & 5(16.875) = 50.625 & 84.375
so, your answer is 50.625 & 84.375
Yes because it is a whole number
Answer:
a 30 b -21
Step-by-step explanation:
a 5x = 5(6)
= 30
b 3y = 3(-7)
= -21
