Answer:
u add 45 + 45 +90 that’s 180 and all triangles equal 180
Step-by-step explanation:
Answer:
k = 13
Step-by-step explanation:
The sum of the angles is 180 since they form a straight line
4k-7 + 90 + 3k+6 = 180
Combine like terms
7k+89=180
Subtract 89 from each side
7k+89-89 = 180-89
7k =91
Divide each side by 7
7k/7 = 91/7
k = 13

<h2><u>Given Expression</u> :-</h2>
<h2><u>Steps to factorise</u> :-</h2>

- Using a²-b² = (a-b)(a+b), factor the expression

- Factor out 2a+3b from the expression


Answer:
see explanation
Step-by-step explanation:
If 2 functions are inverses then the x and y- coordinates swap, that is
(x , y ) → (y, x )
Thus
a = - 3.8 ← the x- coordinate of the inverse
b = - 2.6 ← the y- coordinate of the inverse
c = 1.7 ← the x- coordinate of the inverse
d = 4.4 ← the y- coordinate of the inverse
e = 1.0 ← the x- coordinate of the inverse
