Answer:
m<B = 62°
Step-by-step explanation:
Given that ∆ABC is congruent to ∆TUV, it follows that their corresponding angles are equal to each other. Therefore:
m<B = m<U
m<B = (3y + 2)°
m<U = (4y - 18)°
Thus,
3y + 2 = 4y - 18
Collect like terms
18 + 2 = 4y - 3y
20 = y
y = 20
m<B = (3y + 2)°
Plug in the value of x
m<B = 3(20) + 2
m<B = 60 + 2
m<B = 62°
Answer:
$425
Step-by-step explanation:
Let washer be w
Let dryer be d
If d =x then w=x +74
x+x+74=924
2x+74=924
2x=850
dividing both sides by 2
x=425 hence d which is the dryer is $425
Finds how much is needed for 1 costume by dividing 6 3/4 by 3
6 3/4 /3 = 2 1/4 yards per costume.
Multiply yards per costume by 7:
2 1/4 x 7 = 15 3/4 yards total needed.
N=1,
a1= 48-1*11=48-11=37
a2= 48 -2*11=48 -22=26
d= 26 -37 = -11
a(n) = a(n-1) - 11
a1=37
a(n) = a(n-1) - 11
Check:
a1=37, a2= a1-11 =37-11=26
a3= 48 -3*11=48-33=15 (using explicit formula),
and a3=a2 - 11=26 -11 =15 (the same answer)
Answer is B.
There are a few possibilities, you could have 60 degrees 30 degrees and 90 degrees, for one triangle those added up equal 180 which is needed to make a right triangle. Another possibility would be 45 degrees 45 degrees 90 degrees, those added up equals to 180 degrees. :D
