Answer:
a.) 70*
b.) 60*
Step-by-step explanation:
a.) An isosceles triangle has two angles that are equal. The one other angle is 40*, meaning you have to subtract that from 180 and then divide by 2.
b.) An equilateral triangle has three equal angles. Divide 180 by 3.
Does x equal 4 ?if it does then a) -100
b) 25
They are adjacent because he share a vertex and a common side, and x=15° because 90°/(2+4)= 15
<u>Answer</u>
2,737,152a⁵b⁵
<u>Explanation</u>
(2a - 3b)¹⁰ = (2a)¹⁰ - 10(2a)⁹(3b) + 47(2a)⁸(3b)² - 144(2a)⁷(3b)³ - 212(2a)⁶(3b)⁴ + 352(2a)⁵(3b)⁵
The 6th term in this expression is 352(2a)⁵(3b)⁵
352(2a)⁵(3b)⁵ = 352 × 2⁵a⁵ × 3⁵b⁵
= 352 × 32 ×243 ×a⁵b⁵
= 2,737,152a⁵b⁵
