Answer: [D]: 98°<span> .
______________________________________
Explanation:
______________________________________
Since vertical angles are congruent;
and since </span><span>∠A and ∠B are vertical angles;
then: m</span>∡A = m∡B .
______________________________________
So given: m∡A = 98° ; then m∡B = 98° .

4(2x5 + 3) - 4(2) + 2(5).
4(13) - 18.
52-18 = 34.
ok, b)
you can times anything inside bracket by 8. so, 8r -40 + 12
You can simplify to 8r - 28.
d)
You can rearrange it to 6a + 12a -12/3 -15/3
= 18a - 27/3
Wouldn’t it be 6,054 it so easy
