Answer:
x = 10
Step-by-step explanation:
If you add the angles up, you get 110, so the missing angle is 70. It is an isosceles triangle. The bottom length should be about 11.
Answer:
B) x = 2, y = 3 and z = 5.
Step-by-step explanation:
3x −2y + 4z = 20 .....A
-x + 5y+ 12z = 73 .....B
x + 3y −2z = 1 ......C
Adding B and C:
8y + 10z = 74 .... E
Multiply equation B by -3:
-3x - 9y + 6z = -3
Add this equation to A:
-11y + 10z = 17
Subtract this equation fro E:
19y = 57
y = 3.
Substitute y = 3 in equation E:
8*3 + 10z = 74
10z = 50
z = 5.
Finally substitute y = 3 and z = 5 into equation C:
x + 3(3) - 2(5) = 1
x + 9 - 10 = 1
x = 1 + 1
x = 2.
- 2(3) + 22 - 8 - 2=
-6 + 12 =
6
3 + 3 + 3 + 3 + 3 = 15
3 x 3 x 3 x 3 x 3 = 3^5 (because there are 5 threes multiplied together)
-2x^3 + 22 - 8 - 2 =
-2x^3 + 12
