In the right triangle shown, \angle A = 30^\circ∠A=30∘angle, A, equals, 30, degrees and AB = 8AB=8A, B, equals, 8.

Bogdan [553]

Answer:

BC=4 units

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

In the right triangle ABC

$sin(A)=\frac{BC}{AB}$ ----> by SOH (opposite side divided by the hypotenuse)

we have

$AB=8\ units\\A=30^o$

substitute the given values

$sin(30^o)=\frac{BC}{8}$

solve for BC

$BC=sin(30^o)(8)$

Remember that

$sin(30^o)=\frac{1}{2}$

$BC=(\frac{1}{2})(8)=4\ units$

What is the slope of line segment AB? where A is (-5,3) and B is (3,-3)

Salsk061 [2.6K]

Answer:

D) -3/4

Step-by-step explanation:

Slope is found by using

m= (y2-y1)/(x2-x1) hwere the points are (x1,y1) and (x2,y2)

= (-3-3)/(3--5)

= (-6)/(3+5)

= -6/8

Trey bakes 70 cupcakes for the school Bake Sale. Worried they might run out, he bakes some extra and now has 112 cupcakes.

Ber [7]

Answer:

60%

Step-by-step explanation:

$112:70*100= (112*100):70\\(112*100)=11200\\11200:70=160$

so if 70 is 100%, 112 is 160%

and that is a 60% difference
