Answer:
Step-by-step explanation:
Surface area = lateral area + 2(area of base)
Lateral area = perimeter of base * height.
Because it is a isosceles right triangle, both sides are equal.
= 72
2
= 72. Divide both sides by 2
= 36. Square both sides.
x = 6.
So the perimeter of the base = 6 + 6 +
= 20.485281374239
Lateral area = 20.485281374239 * 7 = 143.397 
Area of base is (1/2)base * height.
(1/2)(6)(6) = 18
Using the surface area formula
surface area = 143.397 + 2(18) = 179.4 
Answer:
1) factor pairs- 1*328, 2*164, 4*82, 8*41
1,2,4,8,41,82,164,328
2) 2^3, 41
not a prime number

Hope this helps you.
Let me know if you have any other questions :-):-)
Hey there! :)
The total measure for triangles is 180°
You already know 2 angles. Add both angles and subtract from 180 to find x
37 + 82 = 119
180 - 119 = 61
m∠x = 61°
Hope this helps :)
1) 462/11= 42
42x7=294
2) 9.38/7= $1.34
3) 6/11= 0.54545454545455
4) 1/4= 0.25
2/9= 0.22222222222
3/10= 0.30
2/1= 2.00
1/5= 0.20
least to greatest- 1/5, 2/9, 1/4, 3/10, 2/1
5) 9/15= 0.6 > 60%
to turn into a percent, move 2 decimal places!
6) 10/4= 2.5
2.5x18= 45
7) 2/3= 0.66666666666
0.66666666666x7= 4.66666666667
