Answer:
Its 48 °
Since its a triangle, the total angle will be 180°
So,
x° + 42°+90°=180°(90° as one angle in triangle is 90°)
x°=180°-90°-42°
x°=48°
Answer:
17/12= 1 5/12
Step-by-step explanation:
Common denominator:
2/3= 8/12
3/4= 9/12
Solve:
8+9= 17
17/12= 1 5/12
Answer:
k = 73
Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees.
62
° + k + 45
° = 180
Solve the equation for k
Add 62
° and 45
°
k + 107 = 180
Move all terms not containing C to the right side of the equation.
Subtract 107 from both sides of the equation.
k = 180 − 107
Subtract
k = 73
0.144 because the number after 3 is 5 and that rounds the 3 to a 4.
