If m1 + m3 = 154°, what is m2

Mathematics

Solution:

we are given that

In Traingle If m1 + m3 = 154°, what is the value of the angle m2.

As we know that sum of angles of a triangle is 180 degree.

Here the sum of the two angles are 154°. So we can find the third angle by subtracting the given sum from 180 degree.

Hence we can write

m_1+m_2+m_3=180^o\\
\\
154^o+m_3=180^o\\
\\
m_3=180^o-154^o\\
\\
m_3=26^o\\

Hence the correct option is A.

snow_lady [41]

Answer:

B) y = 129º

Step-by-step explanation:

since a triangle is 180º in total, the you have to subtract 71 and 58 from 180 which will give you 51º which gives you the amount for x

and the line that the triangle is on is also 180º in total, so you subtract the 51 from 180 to give you a total of 129º which is the amount for y
