Answer:
Step-by-step explanation:
Represent trees with T and wreaths with W
Given
Solving (a): Cost of W
Substitute 3 + 4 * W for T in the second equation
Collect Like Terms
Divide through by 6
Hence, each wreath costs $16
Solving (b): Cost of T
Substitute 16 for W
Hence, each tree costs $67
we know that
The measurement of the exterior angle is the semi-difference of the arcs which comprises
In this problem
∠FGH is the exterior angle
∠FGH=
∠FGH=
-----> equation A
--------> equation B
Substitute equation B in equation A
therefore
<u>The answer is</u>
The measure of arc FEH is equal to
