Given:
In triangle ABC, D is incenter m∠ACB = 3x + 54 and m∠ACD = x + 31.
To find:
m∠ACD.
Solution:
We know that,
Incenter of a triangle is the intersection point of all angle bisectors.
...(i)
Now,
[Using (i)]
Substitute the values, we get
The value of x is 8.
Therefore, the measure of angle ACD is 39 degrees.
The answer is y=120
First you simplify both sides of the equation then u isolate the variable.
Answer:
3/4
Step-by-step explanation:
Answer:
2t
Step-by-step explanation:
The expressions are not the same because different terms are negative. We can visualize the difference by rewriting the expressions as 13t + (-2t) and (-13t) + 2t. In the first expression, 13t-2t, the 2t is negative because it is being subtracted, and subtracting a number is the same as adding a negative.
