The measures of two angles of a triangle are 26 and 98 degrees. Find the measure of the third angle.
2 answers:
In a triangle, the total measure of the interior angles is 180 degrees.
26 + 98 + x = 180
124 + x = 180
x = 56 degrees
The measure of the third angle is 56 degrees.
Hope this helps!! :)
Answer:
Step-by-step explanation:
By the Triangle Angle-Sum Theorem, all the angles of a triangle have to add up to equal 180 degrees. Therefore,
180 - 26 - 98 = 56
The third angle has to measure 56 degrees.

Step-by-step explanation:
Line, point and plane are undefined terms.
7 trials = 0.06×7=0.42
2 trials = 0.06×2=0.12
So 2/7 trials = 0.12/0.42
