Answer:
257/2 degrees or 128.5 degrees
Step-by-step explanation:
radians to degrees is x radians * 180/π
it is 257/2 degrees or 128.5 degrees
The answers are
1) ∠A = 53
°
2) ∠D = 127°
3) x = 5
4) AB = 7
<u>Step-by-step explanation</u>:
In parallelogram,
- Consecutive angles are supplementary (∠A + ∠B = 180°).
- Opposite angels are congruent (∠D = ∠B).
- Opposite sides are congruent (AB = DC).
1) find angle A :
Given, ∠B = 127°
∠A + ∠B = 180°
∠A = 180-127= 53
°
2) find angle D :
Given, ∠B = 127°
∠D = ∠B
∠D = 127°
3) find x :
AB = DC
(x+2) = (2x-3)
2+3 = 2x-x
x = 5
4) find AB
:
AB = (x+2)
AB = 5+2
AB = 7

Answer:
last answer:
h(x) = 1/4 x
Step-by-step explanation:
First, change f(x) to y.
f(x) = 4x
y = 4x
Then switch the x and y.
y = 4x
x = 4y
Last, solve for y.
x = 4y
x/4 = 4y/4
x/4 = y
y = x/4
This is the same as:
y = 1/4 x
h(x) = 1/4 x
Answer:
2 1/3 > 2.3
Step-by-step explanation:
There are a couple of ways you can compare these numbers. One is to convert 2 1/3 to a decimal fraction. It is the repeating decimal ...
2 1/3 = 2.3333333...
Compared to 2.30, we see that 2 1/3 has a 3 in the hundredths place, where 2.3 has 0. Thus 2 1/3 is greater than 2.3.
__
You can convert them both to improper fractions and then to fractions with a common denominator.
2 1/3 = 7/3 = 70/30
2.3 = 23/10 = 69/30
70/30 > 69/30 . . . . so 2 1/3 > 2.3
