Answer:
Measure of angle ADC is 70°
Step-by-step explanation:
So, we know that the overarcing angle BDA equals 110°. And then, we have these two equations that split up this overarcing angle. To solve for x, all we need to do is say is that the sum of these two equations are equal to 110°
2x+10+3x+25=110
Combine like terms
5x+35=110
Subtract 35 from both sides
5x=75
Divide by 5 on both sides
x=15
Now, to find the measure of angle ADC, simply plug 15 in for x on that equation:
3(15)+25
So, the measure of angle ADC is 70°
Answer:
x^3-8
Step-by-step explanation:
x^3+2x^2+4x + -2x^2-4x-8
+2x^2 and -2x^2 cancel out
+4x and -4x cancel out
Answer:
All you need to do is move all terms to the left side and set equal to zero
The Answer is x = 16 Hope this helps :)
