Answer:
105°
Step-by-step explanation:
total angle of triangle equals 180°
so,
25° + 50° + ? = 180°
? = 180° - (25° + 50°)
? = 180° - 75°
? = 105°
So third angle of a triangle is 105°

Answer:
x=-2
Step-by-step explanation:
-4(x-7)=36
divide both sides by four
x-7=-9
move constant to the right and change its sign
x=-9+7
calculate the sum
x=-2
5/4 x 22/45
110/ 180
11/18
Answer:
k=117
Step-by-step explanation:
To solve, we need to isolate the variable, k
k/3 -5 = 34
Add 5 to both sides to "reverse" the subtraction
k/3=39
Multiply both sides by 3 to "reverse" the division
3*k/3=39*3
k=117
Hope this helps! :)
