The answer is 99x. pretend like the variable isn't even there at the beginning. Then at the end put it in next to the answer.
Answer:
142°
Step-by-step explanation:
90°+52°= 142°
180°-142°= 38° (angles in a triangle add up to 180°)
x= 180°- 38° (angles on a straight line is 180°)
x= 142°
3 to fourth power=3^4
3 to ninth power =3^9
Now,
3 to fourth power times to the ninth power=3^4*3^9
the basis same so the powers will add:
3^(4+9)=3^13=1594323
5/10 and 1/2 are both equivalent ratios resulting in half of themselves you can multiply these by any numbers but they will stay as half ratios such as 1:2 x 6 it would be 6:12 divide it by 6 and you have a half
