Answer:

12

Step-by-step explanation:

do 4x+3x+6=90 combine like terms 7x+6=90 subtract 6 from both sides 7x=84

divide both sides by 7 x=12

Since the angles are complementary, and that is a right angle, it is equal to 90°. So, we know that 4x+3x+6=90.

So, solve this for x. Combine like terms. The problem should now look like: 7x+6=90. Now, we need to isolate the x. Subtract 6 from 6, and subtract 6 from 90. This is because we must move the 6 to the other side of the problem to find x. Whatever we do on one side of the problem, we must do on the other. The problem should now look like 7x=84. Now, isolate the variable by dividing 7x by 7. Again, you must do the same thing to both sides of the problem. So, you must also divide 84 by 7.


The answer is x=12.

From his eye, which stands 1.63 meters above the ground, Isaac measures the angle
Shkiper50 [21]

The height of the skyscraper if the angle of elevation to the top of a prominent skyscraper to be 17° is 91.51 meter

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let h represent the height of the skyscraper, hence:

tan(17) = h/294

h = 89.88 meter

Total height = 89.88 + 1.63 = 91.51 meter

The height of the skyscraper if the angle of elevation to the top of a prominent skyscraper to be 17° is 91.51 meter

Answer:

Step-by-step explanation:

Venus = 12000 km = 1.2 * 10⁴

Sun: Venus = 1.4 * 10⁶ : 1.2 * 10⁴

=\frac{1.4*10^{6}}{1.2*10^{4}}\\\\=\frac{1.4}{1.2}*10^{6-4}\\\\=1.17*10^{2}

Draw 8 lines that are between 1 inch and 3 inches long. Measure each line to the nearest fourth inch, and make a line plot.
IRISSAK [1]

The length of the line is the difference between the endpoints of the line

The length of each line to the nearest fourth inch is 0.25 inch

<h3>How to measure the length of each line</h3>

The length of the horizontal line is given as:

Length = 2 inches

This is calculated as:

Length = 3 inches - 1 inch

Length = 2 inches

8 lines are to be drawn between the 1 inch and 3 inches point.

So, the length (l) of each line is:

l = \frac{2\ inches}{8}

Simplify the fraction

l = \frac{1\ inches}{4}

Divide

l = 0.25\ inch

Hence, the length of each line to the nearest fourth inch is 0.25 inch
