avanturin [10]

Answer: Correct Answer is 4th option , 28

Step-by-step explanation:

We can find the measure of the angle using the tangent.

We know, tangent of an angle = Perpendicular/Base, corresponding to that angle.

So, Tan of angle T = RG / RT

or, Tan of angle T = 8/15

or, angle T = tan inverese of 8/15

or, angle T = 28.07

So, angle T rounded to nearest degree = 28

Hope this helps.

Thank you.

3/10 divided by -1/3

Snezhnost [94]

Answer:

-9/10

Step-by-step explanation:

Find the LCM of 10 and 3: 30
Alter the numerators to fit the denominators: 3 × 3 = 9, -1 × 10 = -10
Re-write the fractions: 9/30 ÷ -10/30
9/30 ÷ -10/30 = 9/30 × -30/10
9/30 × -30/10 = -270/300
$-\frac{270}{300} = -\frac{9}{10}$

I hope this helps!

melomori [17]

<span>Determine the values of x on which the function f(x)=2x^2-x-15/4x^2-12x is discontinuous and verify the type of discontinuity at each point.

A.There is a vertical asymptote at 0 and a hole at 3.
B.There are vertical asymptotes at -5/2 & 0 and a hole at 3.
C.There is a vertical asymptote at 3 and a hole at 0.
D.There are vertical asymptotes at 0 & 3.

Result:
(-7/4)x^2-13x

The roots are:
x= -52/7
x=0
