Answer:
B.) 113°
Step-by-step explanation:
In the isosceles trapezoid, angles T and S are congruent. Find the value of x:
Subtract 4x from both sides:
Add 38 to both sides:
Divide both sides by 3:
x is equal to 15. Now substitute the value of x into the one of the expressions:
or
The angles T and S are 67°.
The angles of a trapezoid will always add up to a total of 360°, so add the angles T and S:
Subtract their total from 360:
The total of the angles Q and R is 226°. Since this is an isosceles trapezoid, those two angles are also congruent. Divide the value by 2:
Angle R is 113°.
Done.
The axis of symmetry is x=2.
a. If you double both sides, you'll get a rectangle with dimensions 20 feet wide and 30 feet long, therefore the area will be 20 × 30 = 600 feet².
b. The area of the old rectangle was 10 × 15 = 150 feet², so no the area is not twice as large, it is 4 times as large. This is because if the area is base × height, then doubling both of these gets you (2 × base) × (2 × height) = 4 × (base × height).
I hope this helps!
If you can give me more information on this I could help you a bit more respond.
Answer:
No
Step-by-step explanation:
If they are a Pythagorean triple, then the square of the largest number will equal the sum of the squares of the other 2 numbers.
largest number = 9 and 9² = 81
6² + 8² = 36 + 64 = 100 ≠ 81
Thus 6, 8 and 9 are not a Pythagorean triple
