Answer:
22
Step-by-step explanation:
25+23=48+22=70 in degree
Answer: 11
Step-by-step explanation:
Complementary angles mean both angles sum 90°, then:
(3x + 2)° + 5x° = 90°
3x° + 2° + 5x° = 90°
8x° + 2° = 90°
8x° = 88°
x = 11
Confirmation:
(3x + 2)° 5x°
(3(11) + 2)° 5(11)x°
(33 + 2)° 55x°
35°
35° + 55° = 90°

Answer:
21 meters and 29 meters
Step-by-step explanation:
x + (x + 8) = 50
2x + 8 = 50
2xc = 42
x = 21
x + 8 = 29
Answer:
x = 13
y = -10
z = -7
Step-by-step explanation:
x+y+z=−4
2x+3y−2z=10
−x+2y−3z=−12
Add the first and the third equations to eliminate x
x+y+z=−4
−x+2y−3z=−12
--------------------
3y -2z = -16 Equation A
Add the second and twice the third equation to eliminate x
2x+3y−2z=10
−2x+4y−6z=−24
----------------------------
7y -8z = -14 Equation B
Take Equation A and multiply by -4
-4*( 3y -2z) = (-16)*-4
-12y + 8z = 64
Add this to Equation B
-12y + 8z = 64
7y -8z = -14
-----------------------
-5y = 50
Divide by -5
-5y/-5 = 50/-5
y = -10
Now using equation A
3y -2z = -16
3*-10 -2z = -16
-30 -2z = -16
Add 30 to each side
-2z = -16+30
-2z = 14
Divide by -2
-2z/-2 = 14/-2
z = -7
Now find x using the first equation
x+y+z = -4
x -7-10 = -4
x -17 = -4
Add 17 to each side
x-17+17 = -4+17
x = 13
