Answer:
y = 43°
Step-by-step explanation:
The unknown angle x inside the quadrilateral is adjacent to 80° and sum to 180° , then
x = 180° - 80° = 100°
The sum of the 4 interior angles of a quadrilateral = 360°
sum the 4 angles and equate to 360°
y + 145° + 72° + 100° = 360° , that is
y + 317° = 360° ( subtract 317° from both sides )
y = 43°
6/11y=-18/22
Least Common Denominator is 11: 6/11y=-9/11
Multiply both sides by 11: 6y=-9
Divide both sides by 6: y=-9/6
Simplify: y= -3/2 OR -1.5
7x-2x+15=10
5x+15 = 10
- 15 (on both sides, cancels out on the left side)
5x= -5
÷5 (on both sides, cancels out on the left)
x = -1
I hope that helped! ☺♥
I had this problem for rsm too if you go there anyway the answer is 49 outside of the square root and the 3 is in the square root and then divided by 2.
Co linear points have same slope
<span>Points (1,3), (-4,7), and (-29,K)
m1,2=7-3/-4-1=-4/5
m2,3=K-7/-29+4
m2,3=K-7/-25
-4/5=K-7/-25
4/5=K-7/25
4=K-7/5
20=K-7
K=27
