Angle BCA = 180 - 100
angle BCA = 80
Isosceles triangle ABC has two congruent angles, A and B
2x + 80 = 180
2x = 100
Angles A and B = 50 or y and z = 50
I think lines AB and DE are supposed to be parallel, so angles y and x are consecutive interior angles (supplementary)
x = 180 - 50 = 130
Answer:
Step-by-step explanation:
<u>Given the sequence </u>
<u>We see it is an AP with</u>
- The first term a = 13
- Common difference d = 13 ( as 26 - 13 = 39 - 26 = 13)
<u>The 12th term is:</u>
- a₁₂ = a + 11d = 13 + 11*13 = 156
i think is is right but i’m not 100% sure
Answer:
The value of function (fog)(x) is 4 x² - 19
Step-by-step explanation:
Given function as :
f(x) = 4 x + 1
g(x) = x² - 5
So , function (fg(x)) can be written as
(fog)(x) = 4 ( x² - 5 ) + 1
Or, (fog)(x) = 4 x² - 20 + 1
Or, (fog)(x) = 4 x² - 19
Hence The value of function (fog)(x) is 4 x² - 19 Answer
