Answer:

Step-by-step explanation:

tan x= 6/8

usually tan θ = perpendicular / base

So,

we get perpendicular = 6, base = 8

Now using Pythagorean Theorem to find hypotenuse

hyp² = base² + Perp²

hyp² = 8² + 6²

hyp²= 64 + 36

hyp²=100

Taking sq root on both sides

hypotenuse = 10

Now

sin θ = Perpendicular / Hyp

sin x = 6 / 10

Now

cos θ = base / Hyp

cos x = 8 / 10

Answer:

$x=\frac{26}{5}$

Step-by-step explanation:

$\frac{10x+4}{7}=8$

Multiply both sides by 7:

$\longmapsto$ $\frac{7\left(10x+4\right)}{7}=8\times \:7$

$\longmapsto$ $10x+4=56$

Subtract 4 from both sides:

$\longmapsto$ $10x+4-4=56-4$

$\longmapsto$ $10x=52$

Divide both sides by 10:

$\longmapsto$ $\frac{10x}{10}=\frac{52}{10}$

$\longmapsto$ $x=\frac{26}{5}$

Six times the lesser of the two consecutive even integers is 4 times the greater even integer. What are the integers?

Paladinen [302]

Answer:

Integers are 4 and 6

Step-by-step explanation:

Let the two consecutive even integers be $x,x+2$ such that $x$

Six times the lesser of the two consecutive even integers is 4 times the greater even integer.

So,

$6x=4(x+2)\\6x=4x+8\\6x-4x=8\\2x=8\\x=4$

Other integer $=x+2=4+2=6$

A star-patterned quilt has a star with the angles shown. What is the value of X? The diagram is not to scale.

hodyreva [135]

I want to say 81°

Here's how I found that:

The angle 105° is on a straight line showing the outer obtuse angle. A straight line is 180°.
180-105=75.
Therefore that inner angle of the 105° is 75°.

We are also given the top angle of 24°.

All 3 angles of a triangle should add up to 180. So, we get the 75+24=99
180-99=81

Last angle should be 81°
