Answer:
240
Step-by-step explanation:
When doing proportions you multiply the numerator of one fraction by the denomenator of the other. Here the available pair is 19.2 and 25. This means that we multiply 19.2 by 25, which equals 480. The next step is to divide by the remaining numerator or denomenator. Here we divide 480 by 2, which equals 240.
Answer:
Since we can see that angle L and angle C are supplementary angles, we have the following equation:
∠C + ∠L = 180°
Therefore to find the measurement of angle C, we need to subjact the measurement of angle C from 180°:
∠L = 180° - ∠C
Answer:
x = 25 degrees
Step-by-step explanation:
So we know that the 4x, 2x + 10°, and x - 5° and the measures of the three interior angles of the triangle. The sum of the interior angles of a triangle is 180°.
Using this, we can conclude that the sum of 4x, 2x + 10°, and x - 5° is equal to 180°.
We can write this information as the equation:
4x + (2x + 10) + (x - 5) = 180
We can use this equation to find the value of x. To find the value of x by using the equation, we need to solve for x (put the equation into the form x = _).
Solve for x:
4x + (2x + 10) + (x - 5) = 180
4x + 2x + 10 + x - 5 = 180
Combine like terms.
7x + 5 = 180
Subtract 5 from both sides to get rid of the +5 on the left side.
7x = 180 - 5
Simplify.
7x = 175
Divide both sides by 7 to get rid of the coefficient of 7 on the left side.
x = 175 ÷ 7
Simplify.
x = 25.
x would be equal to 25°.
x = 25 degrees

Answer:
q=15
Step-by-step explanation:
1/5q=9-2/5q
Multiply both sides by 5
q=9*5-2q
3q=45
q=15
