Answer:
3x-22=80+x
3x-x=80+22
2x=102
x=51
Step-by-step explanation:
the exterior angle is (3x-22) and then is equal to sum of 80 and x
and then we get 51
Answer:
cool, how long did it take
Four times the sum of x and two
Answer:
x = 58°
Step-by-step explanation:
The sum of the angles in Δ AHI = 180 , then
∠ AIH = 180° - (66 + 56)° = 180° - 122° = 58°
x and ∠ AIH are corresponding and are congruent , then
x = 58°
Answer:
2
Step-by-step explanation:
An arithmetic progression with first term a and common difference d has the following first 6 terms:
a, a + d, a + 2d, a + 3d, a + 4d, a + 5d
We are given a = 1 and a + 5d = 11.
1 + 5d = 11
5d = 10
d = 2
Answer: The common difference is 2.
