Answer:

ngle A=77

Angle B=103

Step-by-step explanation:

∠A+∠B=180 ( supplementary  angles)

3/8 x  +50+x+31=180

3/8 x+x=180-81

11/8 x=99

11x=99*8

x=(99*8)/11 =72

Angle A= 3/8 (72)+50

Angle A=27+50=77

Angle B= 72+31=103

Answer:

m<a = 77

m<b= 103

Step-by-step explanation:

m<a+m<b = 180(supplementary angles)

3x/8+50+x+31=180

3x/8+x+81=180

(3x+8x)/8=180-81

3x+8x=99*8

11x=792

x=792/11

x=72

now

m<a=3x/8+50

=(3*72)/8+50

=77

m<b=x+31

=72+31

=103

Multiplying to Fractions 
ExtremeBDS [4]

Answer:

B. No. The product of two fractions is the product of the numerators divided by the product of the denominators.

Step-by-step explanation:

For A: A is clearly false because you can multiply any fraction and it doesnt matter what the denominator is.

For B: The first part is correct, which is that to multiply two fractions, they dont have to have like/common denominators, the explanation part is also correct. When we multiply we multiply the numerator to the numerator and the denominator to the denominator.

For C: C is false because the first part says yes and we know that you can multiply any 2 fractions regardless of denominators.

For D: For D the first part is correct however, the explanation section is false you dont multiply the numerator to the denominator.

For E: You don't have to find the equivalent fraction to multiply because you can do that afterward.

I hope this helps, have a blessed day! :D

Line h contains the points (3,0) and (0,4). which point lies on a line that is perpendicular to line h and passes through point
Iteru [2.4K]
(3,0)(0,4)
slope = (4 - 0) / (0 - 3) = -4/3
A perpendicular line will have a negative reciprocal slope. So our perpendicular line has a slope of 3/4

y = mx + b
slope(m) = 3/4
(-6,-5)....x = -6 and y = -5
now sub into the formula and find b, the y int
-5 = 3/4(-6) + b
-5 = -18/4 + b
-5 + 18/4 = b
-20/4 + 18/4 = b
-2/4 = b
so ur perpendicular line is : y = 3/4x - 2/4....or 3x - 4y = 2

and ur point (6,4) lies on the perpendicular line <===
