Answer:

The measure of angle A is 32 degrees

Step-by-step explanation:

The picture of the question in the attached figure

In the right triangle of the figure

The tangent of angle A is equal to

tan(A)=\frac{5}{8} ----> by TOA (opposite side divided by the adjacent side)

Find the measure of angle A

using a calculator

A=tan^{-1}(\frac{5}{8})=32^o

If 2x – 10y = -1 and 5x + 6y = 4 are true equations, what would be the value<br> of 7x - 4y?
Zigmanuir [339]

Answer:

Step-by-step explanation:

If the equations are true, they can be solved simultaneously.

Consider 2x-10y=-1 as Eq1 and 5x+6y=4 as Eq2

Multiplying Eq1 with 3 and Eq2 with 5 we get,

6x-30y=-3 -- Eq3 and 25x+30y=20 -- Eq4

Adding Eq3 and Eq4,

31x=17 Therefore, x=17/31

Plugin x=17/31 in Eq3,

6(17/31)-30y=-3 --- y=13/62

Plug In values of x and y in 7x-4y we get,

7(17/31)-4(13/62) = 3

So the value of 7x-4y = 3.

Divide.<br> Write your answer in simplest form.<br> 1/9÷5/4=
irina [24]

Answer:

4/45

Step-by-step explanation:

when dividing fractions, you multiply the first fraction by the second fraction's reciprocal :

1/9 divided by 5/4

1/9 multiplied by 4/5

essentially, you switch the signs from division to multiplication, and reverse the second fraction.

1/9 multiplied by 4/5

1/9*4/5 = 4/45
