we are given
DEF is a line
so, sum of angles must be 180
angle(DEG)+angle(GEF)=180
now, we can plug values
.........Answer
vertically opposite angle must be equal
angle(GEF)=angle(DEH)
now, we can plug values
now, we can plug x=16
...................Answer
Answer:
Step-by-step explanation:
by inspection
angles 2 and 3 are equal, so they will be half angle ABC
angles 1 and 5 are equal so they will be
angle 1 + angle 5 + angleABC = 180° kind of a rule for triangle
the sum of all angles - 180°
(angle 1) x 2 = 180° - 70°
angle 1 = 90° - 35°
angle 1 = 55° which equals angle 5
angle 4 is clearly a right angle 90°
DO the same procedure for the bottom triangle
angle 8 and 9 are half of angle ADC
angle 8 and 9 are half of 46°
both are 23°
angle 6 equals angle 7
2 ×angle 6 = 180° - 46°
angle 6 = 90° - 23°
angle 6 = 67° angle 7 = 67°
Did I find them all
Answer:
-7
Step-by-step explanation:
The numerical coefficient of 
is - 7.
Answer:
Step-by-step explanation:
Brayden's car travels 37.1 miles per gallon.
Dylan's car travels 48.4 miles/(2 gallons) = 24.2 miles per gallon.
37.1 - 24.2 = 12.9
Dylan's car gets 12.9 miles per gallon less than Brayden's car.
The value of a right angle is 90°, equal 12x-9 to 90 to find x.
12x-9=90
Add 9 to both sides.
12x=99
Divide both sides by 12.
x=8.25
