Answer:
M. 2.5n - (-8.2) = 26. 7
to find n transpose
2.5n + 8.2 = 26. 7
2.5n = 26. 7 - 8.2
2.5n = 18.5
n = 18.5 ÷ 2.5
n = 7.4
L. = 18
7a + 1 = 18 ×2
7a + 1 = 36
7a = 36 - 1
7a = 35
a = 35 ÷ 7
a = 5
N. b + 1 = -11
b = -11 -1
b = -12
b = -12 -
b = 20
H. 5 - d = 32
- d = 32 - 5
- d = 27
d = 27 +
d = 6
Answer:
The measures of angles of triangle EFQ are
1)
2)
3)
Step-by-step explanation:
step 1
Find the measure of arc QD
we know that
The inscribed angle is half that of the arc it comprises.
substitute the given value
step 2
Find the measure of arc FQ
we know that
---> because ED is a diameter (the diameter divide the circle into two equal parts)
substitute the given values
step 3
Find the measure of angle EFQ
we know that
The inscribed angle is half that of the arc it comprises.
substitute the given value
step 4
Find the measure of angle FEQ
we know that
The inscribed angle is half that of the arc it comprises.
substitute the given value
step 5
Find the measure of angle EQF
we know that
The inscribed angle is half that of the arc it comprises.
substitute the given value
