Given:
and
are complementary angles.

To find:
The measure of
.
Solution:
According to the definition of the complimentary angles, the sum of two complementary angles is always 90 degree.
It is given that,
and
are complementary angles. So,




Therefore, the measure of
is 58°.
Answer:
10
Step-by-step explanation:
As we can see in hint through it we can identify that it is right angled triangle so here
AB = 6
FE = BC ( being corresponding sides of congruent triangle)
BC = 8
Now In triangle ABC
perpendicular (p) = 6
base (b) = 8
hypotenuse (h) = ?
By using Pythagoras theorem we get
h = √ p² + b²
= √ 6² + 8²
= √ 100
= 10
So Now
AC = h = 10
