∠1 and ∠2 are complementary.
∠1 + ∠2 = 90°
Question a:
∠1 = 23°
∠2 = 90 - 23 = 67°
Ans: 67°
Question b:
∠1 = x
∠2 = 2x + 3
x + 2x + 3 = 90
3x + 3 = 90
3x = 90 - 3
3x = 87
x = 29
∠1 = 29°
∠2 = 2(29) + 3 = 61°
Ans: ∠1 = 29°, ∠2 = 61°
Step-by-step explanation:
2(x+10)=60
x+10=60/2
x=30-10=20
Answer:
A'(4,-6) , B'(0,1), C'(-2,-2)
Step-by-step explanation:
From the given graph the coordinates of ΔABC area A (2,-2), B(-2,5) and C(-4,2)
If a translation is applied on ΔABC two units to the right and four units down to create ΔA'B'C'.
Then to find the coordinates of ΔA'B'C' will be we need to apply the translation rule

Now, 

and 
Answer: x = 121 degrees
Step-by-step explanation:
(n-2) x 180
(6-2) x 180
4 x 180=720
599 +x = 720
599 - 599 = x +x = 720 - 599 = 121
and then add up all the degrees
88 + 105 + 142 + 140 + 124 + 121 = 720
so there for you answer for x is 121 degrees
The answer to your question is D- ellipse
hope this helps :D
