m DBC 90 and m

m < DBC= 90, and m <2=28. Find m <1

Solution

Solution:

Given m < DBC = 90, and m < 2 = 28

Now we have to find m <1

We know that a triangle with 3 angles will add upto 180 degrees.

Assume m <1 = x

m < DBC + m <2 + m<1 = 180⁰

90 + 28 + x = 180⁰

118 + x =180⁰

x = 180-118

x = 62⁰

x = 62⁰

Hence m<1 = 62⁰
