Answer:
Therefore the value of x is 25.8 unit.
Step-by-step explanation:
Given:
AB =Tangent = y
BE = secant segment = 5
BC = secant segment = 7
EF = x
CD = 15
To Find :
x = ?
Solution:
Tangent-secant theorem:
"When a tangent and a secant are drawn from one single external point to a circle, square of the length of tangent segment must be equal to the product of lengths of whole secant segment and the exterior portion of secant segment."
Here we have
AB =Tangent
BC = secant segment = 7
BD = exterior portion of secant segment = BC +CD =7 + 15 = 22
So on applying Tangent-secant theorem we get
Substituting we get
Now again applying Tangent-secant theorem for different secant we get
Substituting we get
Therefore the value of x is 25.8 unit.
4+P and in subtaction will be P - 4... because in subtraction the letter always goes first and the number next.
Factor by grouping.

Answer:
The measure of the third angle is 117 degrees and the measure of the two equal angles is 31.5 degrees
Step-by-step explanation:
<u><em>The correct question is</em></u>
A geodesic dome is compromised of two different types of triangular panels. One of these is an isosceles triangle. In one geodesic dome, the measure of the third angle is 85.5 degrees more than the measure of either of the two equal angles. Find the measure of the three angles
we know that
An isosceles triangle has two sides and two equal interior angles
Let
x -----> the measure of the third angle
y ----> the measure of either of the two equal angles
we know that
-----> equation A
-----> equation B
substitute equation B in equation A and solve for y
therefore
The measure of the third angle is 117 degrees and the measure of either of the two equal angles is 31.5 degrees
