Answer:
y=63, x=20, x=47, b=70, c=89, x=133
Step-by-step explanation:
1) y=63- alternate angles are the same
2) 4x+5x=180
9x=180
x=20
3) x=47
4) b=70- angles on a line equal to 180
c=89- angles in a triangle add up to 180
5) x=133- angles that are alternate are the same
It is a 30,60,90 triangle, so x = 4, and y = 2
Answer:
27
Step-by-step explanation:
1+2=3
3+4=7
7+8=15
15+12=27
Answer:
y=x^2
Step-by-step explanation:
if you look at it, x is constantly multiplying itself so-
Answer:
We know that 5x-3x =2x
So x(5x-3x)=x×2x
=(2x)^2
=4x^2
Which is given as 18.
X^2=18÷4
=4.5
So x=root over 4.5
Which is approximately 2.123
