Answer:
B
Step-by-step explanation:
Answer:
39
Step-by-step explanation:
Let's first take the ones with numerical values into play. If you add the second and the third equations, you get 10 = 2(shoe), so the shoe is 5. Then the helmet is 4. Taking the first equation, shirt-5=4+4, so shirt = 8+5=13. Then, we have Goal post = 4+13=17. The question mark is 13+9+17=39.
X-5y=-21
x=-21+5y
-6(-21+5y)+4y=10
126+-30y+4y=10
126+-26y=10
-26y=-116
y=4.4615
x=1.3076
Answer:
m<1=92°
m<2=88°
m<3=92°
m<4=88°
Step-by-step explanation:
if m<4=88°, then m<2=88° as vertically opposite angles are equal
angles 1 and 3 are also vertically opposite.
If we let angle 1 =x, then angle 2=x as well
adding them both gives 2x. Angles at a point add up to 360, so:
88+88+2x=360
176+2x=360
2x=184
x=92
