Answer:
x = 11
m<H = 39°
Step-by-step explanation:
m<G = 6x - 15
m<H = 3x + 6
complementary angles = angles that add up to 90
6x - 15 + 3x + 6 = 90
9x = 99
x = 11
m<H = 3x + 6, plug in 11 as x
3 * 11 + 6
= 33 + 6
m<H = 39°
Answer:y=7 x=14 z=-5
Step-by-step explanation:
For the equation, we need to use the substitution method. So first we will use the y+2z=-3 and subtract 2z from both side and get y=-3-2z. then we will substitute the y in the 2+y+3z=-6 with y=-3-2z so it will be 2+(-3-2z)+3z=-6. then we combine the like-term so it will be -1+z=-6 then add both side with 1 and get z=-5. substitute the z in the y+2z=-3 with -5 and get y-10=-3 then add 10 to both side to get y=7 then substitute the y in the x-2y+z=-5 with 7 and z with -5 so the equation will be x-19=-5 then add the 19 on both side to get x=14.

Answer:
114
Step-by-step explanation:
to get the degrees of hexagon u should know first the greatest degree so you can subtract the others from it and how to get that
by this formula (no of sides-2)*180
(6-2)*180=720
so 138+128+120+160+90=606
and the remaining angle should be 720-606
which is 114
