angle GAL would be the same as MLA
Answer:
53.13
Step-by-step explanation:
mJKL = sin-1(9/15) = 36.9 deg
mKJL = = 36.9 deg ...base angles of isosceles triangle JKL
mJLK = 180 - 36.9 - 36.9 = 106.26 deg
mJPK = mJLK/2 = 106.29/2 = 53.1 deg......half of central angle
Answer:
Linear pair is a pair of adjacent angles formed when two lines intersect.
so, and are linear pairs.
Linear pairs are always supplementary.
therefore,
......[1]
Also, it is given in figure,
Substitute in [1], we get;
Simplify:
Exterior- Angle sum Property states that if the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles of the triangle.
then by Exterior angle sum property ;
Substitute the values given in the figure;
simplify;
therefore, the measure of angle ACB is,
There are no linear pairs.
For <1 and <3 to be linear pairs they would have to be adjacent and add up to 180.
