Answer:
angle x = 98
angle y = 82
angle z = 82
Step-by-step explanation:
angle y + 98 = 180; therefore, angle y = 82 degrees
angles z and y are alternate interior angles and are congruent (equal)
angle x is 98 degrees because angles x and y are same-side interior and their angles are supplementary (add up to 180 degrees)
Answer:
196.48
Step-by-step explanation:
Area of the semi-circle:
A= (πr^2)/2
A= (3.14 x 64)/2
A= 100.48
Area of triangle:
A= 1/2bh
A= 1/2(16)(12)
A= 96
96 + 100.48= 196.48

Answer:
50
Step-by-step explanation:
must use PEMDAS (order of operations)
step 1: multiply 7 and 6
8 + 42 / 3 x 3
step 2: divide 42 by 3
8 + 14 x 3
step 3: multiply 14 and 3
8 + 42
Add to get 50
Answer:
42.9
Step-by-step explanation:
There are many ways to answer this one, the most direct way would be to state that tan(65)=a/20
20tan(65)=a
Using the calculator (set in degree mode)
we find that a ~ 42.9
