Step-by-step explanation:
his father's age= 4x
his mother's age= 4x- 7
his age= x
x+4x+4x-7=101
x+ 4x+ 4x= 101+ 7
9x= 108
=
x= 12

bc you multiply 1/2 and 5 first then you subtract 11 1/2 by 8
Answer:
Measure of and in degrees.
Step-by-step explanation:
Given:
A parallelogram where angles A and D measures same also, C and B measures same.
According to the question:
Measure of angle C is twice the measure of angle A.
Let the measure of angle A be "x" degree.
Accordingly :
Measure of each angle C and B = "2x"
Measure of each angle A and D ="x"
Note:
The sum of the measures of the angles of a parallelogram is 360°.
⇒
⇒
⇒
⇒
So,
Measure of angle A and D be 60 degrees each.
Measure of angle B and C is 120 degrees each.
Answer:
x:
5x - 29 = 3x+ 19
2x = 48
x = 24°
Angle 1:
180 - (3x+7) = 180 - 79 = 101°
Angle 2:
3x + 7 = 79°
Angle 3:
Same as Angle 1 = 101°
Angle 4:
Same as Angle 1 = 101°
Angle 5:
Same as Angle 2 = 79°
Angle 6:
Same as Angle 5 = 79°
Angle 7:
180 - (5x - 29) = 180 - 91 = 89°
Angle 8:
Same as Angle 7 = 89°
Angles 2 and 3 are Supplementary angles
