The way you do this is by creating a system of equations:
5x - 10 = 4x + 12
Then you solve the system:
5x - 4x = 12 + 10
x = 22
Substitute x back into DEC and you get (4(22) + 12)<span>°
Which is 100</span><span>°
Hope this helps!</span>

In ΔJKL, the measure of ∠L=90°, KL = 22 feet, and JK = 54 feet. Find the measure of ∠J to the nearest degree.
nydimaria [60]

We have been given that in ΔJKL, the measure of ∠L=90°, KL = 22 feet, and JK = 54 feet. We are asked to find the measure of angle J to nearest degree.

First of all, we will draw a triangle as shown in the attachment.

We can see from our attachment that side KL is opposite side to angle J and side JK is hypotenuse of right triangle.

We know that sine relates opposite side of right triangle to hypotenuse.

\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}

\text{sin}(\angle J)=\frac{22}{54}

Using inverse sine or arcsin, we will get:

\angle J=\text{sin}^{-1}(\frac{22}{54})

\angle J=24.042075905756^{\circ}

Upon rounding to nearest degree, we will get:

\angle J\approx 24^{\circ}

Therefore, the measure of angle J is approximately 24 degrees.

lemon squash 2 parts concentrate to 5 parts of water. if you put 90ml of concentrate in a glass, how much water should be added?
snow_lady [41]

It is given in the question that in the lemon squash 2 parts concentrate is added to 5 parts of water. Thus it makes the concentrate to water ratio as 2:5 or \frac{2}{5}. Now, if this ratio is maintained then the amount of water to be added to 90 ml concentrate in a glass can be calculated as:

\frac{2}{5}=\frac{90}{x}

Where x is the amount of water to be added, in ml (milliliters).

Cross multiplication of the above equation will give us:

2x=90\times 5=450

Dividing both sides by 2 we will get:

x=\frac{450}{2}=225

Thus, if we put 90ml of concentrate in a glass, the water that should be added must be 225 ml.
