Answer:
1) 51° 2) _?_ 3) 55 ⁰ 4) 30°
Step-by-step explanation:
3) First you find out what is G which = 90⁰, And then add the 90 and 75.
Then we will make this equation : (90+75) - 360 ( because Angle Sum property = Sum of all angles from the inside = 360⁰)
Then we do that which will be = 185-360
= 175
The we plus all the x's = x + 2x
= 3x
then our equation is = 3x= 175
x = 175/3 (Because of Transposition )
x= 55°
And Then we do add and multiply
Like This: x=55
2x= 2x55 = 110°
1) First add 67 and 62
Then our equation= (67+62)-180 ( Because of Interior angle sum property of triangles = sum of all interior angles = 180°)
Then = 129 - 180
= 51 °
And then because of opposite angle are equal so our x= 51° because our angle in the triangle above x = 51° so it will be equal opposite (hope you understand)
4) First add 2x+4x
Our Equation= (2x+4x)=90° (be cause right angle = 90°)
= 6x=90
x =90/6
x = 15°
So, 2x= 2 x 15 = 30°
4x = 4 x 15 = 60°
2) Sorry I don't know the second one but i tried solving it but one favor can you please make another question for the second one in brainly so i can answer there.
