Suppose the width is w
Then the length will be w+4
Perimeter will be 2 (length + width) = 2 (w + w + 4 ) = 60
Solve this for w. Knowing w you can find the length and width.
The measure of the missing angle(a) in the isosceles triangle(two sides and angle equal) is 70 degrees.
<h3>What is an Isosceles triangle?</h3>
An Isosceles triangle is a triangle that has two of it sides equal to each other and two of it angles equal to each other.
The base angle of an isosceles triangle are equal. Therefore, let's find angle a in the triangle.
55 + 55 + a = 180
Recall the sum of angle in a triangle is 180 degrees.
110 + a = 180
subtract 110 from both sides
110 - 110 + a = 180 - 110
a = 70 degrees

Answer:
alr i tried, i hope i got them right! <3 pls let me know if i got them wrong.
1. 108 | 6x12 = 72 9x12 = 108 |
2. 91 | 13x7 = 19
3. 19 | 108/6 90/6 = 19/15 |
4. 50. 400/8 = 50
5. 50. 300/6
hope this helped! <3

B={8,9,10,11}
now,
AUB={3,4,7,9}U{8,9,10,11}
={3,4,7,8,9,10,11}
hope it helps.
5/4 you do the multiple add combo and then multiply straight across
