The answer is 35
Since they are supplementary they both equal 180 degrees.
(3x+10)+(2x-5)=180
Add them up
5x-5=180
Subtract 5 from both sides
5x=180-5
5x=175
Divide 5 from both sides
x=35.
Answer: It's (3,-2)
Step-by-step explanation:
Answer:
3 and 9
Step-by-step explanation:
3 * 24 = 72
9 * 8 = 72
3 * 15 = 45
9 * 5 = 45
In left one)
the 3 angles are equal so the sides are equal then we can say

then x is 30÷11
the right one) is exactly similar
16/1 *4/3
16*4 then divide that answer by 3.
