A) 13 degrees because it would be 90-77
If two angles are complementary, then the two angles add up to 90 degrees.
If angle A is 77, then the complement would be 90-77 or 13 degrees.
b) The complement of the complement of the angle is the angle itself.
Say the angle A is 30 degrees. It's complement is 90-30 or 60 degrees.
The complement of the 60 degrees is 30 degrees.
So the complement of the complement of the angle would be the angle itself.
Hope this helps :)
Answer:
0.796
Step-by-step explanation:
40% of 1.99
40/100 × 1.99
0.4 × 1.99 = 0.796
Answer:
x and y are both equal to 57.5°
Step-by-step explanation:
180° - 65° = 115°
115 ÷ 2 = 57.5
For this question we will use the following relations.
100 centimeters=1 meter (or 1 centimeter= 0.01 meter)
10 millimeter=1 centimeter (or 1 mm=0.1 cm)
60 minutes = 1 hour (or 1 min=
hour)
Now, Jackson's speed is 1350 meters per hour. This can be converted to cm per minute as follows:
...Equation 1
Likewise, Jonah's swim speed in cm/min can be calculated as:
...Equation 2
As we can see clearly after comparing Equation 1 and Equation 2, Jonah's swim speed of 7500 cm/min is faster than that of Jackson.
Thus, option B is correct.
Solution of equation 4-2(x-5)=x-19 is given below .
Step-by-step explanation:
4-2(x-5)=x-19
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4-2*(x-5)-(x-19)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(4 - 2 • (x - 5)) - (x - 19) = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
33 - 3x = -3 • (x - 11)
Equation at the end of step 3 :
-3 • (x - 11) = 0
Step 4 :
Equations which are never true :
4.1 Solve : -3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : x-11 = 0
Add 11 to both sides of the equation :
x = 11
One solution was found :
x = 11
