CD bisects angle C, so makes these ratios proportional:
.. AD/AC = BD/BC
.. 3/4 = x/7.5
.. x = 7.5*(3/4) = 5.625
1. x=6
2. x=4
3. x=3.5
please mark me brainliest i really need it to move up!! yeah
Answer:
90
Step-by-step explanation:
because its a right triangle
A triangle's interior angles will add up to be 180°. If you take what you have...the 39° and 141°...and add them up to be 141. Subtract the 141 from the 180° and you will get the value of x...
x° = 39°
Answer:
x = -35
Step-by-step explanation:
multiply both sides by 5
5x/5 = 5(-7)
simplify
x = -35
