Answer: x=1.2
Why?:
This is a 90-60-30 triangle
The sides of 90-60-30 triangle are: 2, square root of 3, 1
2.4/2 = x/1
2.4/2=2x/2
1.2=x
Hope this’ll help
4x ( 2x^3-x^2-18x+15)=
4(2)x^(1+3)-4x^(1+2)-4(18)x^(1+1)+4(15)x=
8x^4-4x^3-72x^2+60x
Answer:
the answer is 10x^2-30x+20
Step-by-step explanation:
you have to distribute the numbers and multiply then add the matching variables.
M<1 = 90 degrees. Since line B is perpendicular to line c, angle 5 and angle 6 are both 90 degrees (they bisect each other). Since angle 5 is 90 degrees, and corresponds to angle 1, angle 1 must also be 90 degrees.
