The answer would be 42° because a triangle equals 180° and you know 2 angle measurements, 48 and 90.
48 + 90 = 138
180 - 138 = 42°
(You know one angle is 90° because supplementary angles equal 180°)

Answer:
Width is 10ft and length is 6ft.
Step-by-step explanation:
The area of a shape is the amount inside a shape. It is found using multiplication or A = l*w. Since the width is w and the length is 4ft less than its width or w - 4, use these expressions in the area formula to find their amount.
Subtract 60 from both sides and factor the quadratic to solve for w.
Set each factor equal to 0 and solve.
w - 10 = 0 so w = 10
w + 6 = 0 so w = -6.
Since w represents a length or distance it cannot be negative, this means the width is 10. The length which is w - 4ft is 10 -4 = 6. The length is 6 ft.
Answer:
Step-by-step explanation:
"COUNTY FAIR" involves 10 letters
<h3>Part A</h3>
<u>The probability of winning is 10 out of 26:</u>
<h3>Part B</h3>
<u>Expected number of winners with 52 contestants:</u>
The experiment result is almost twice less (12 vs 20).
In order to change the results of experimental probability some of the letters may need swapped, (probably the letters are in alphabet order) but for this we need more data.
