We have been given that the hypotenuse of a right triangle is equal to 1.2 cm and the interior angles are 60 degrees, 30 degrees, and 90 degrees.
We know that hypotenuse corresponds to 90 degrees angles.
We also know that the hypotenuse is equal to twice the length of the shorter leg and shorter leg is the opposite side to 30 degree angle.
To find the length of shorter leg, we will divide length of hypotenuse by 2.
Therefore, length of shorter leg is 0.6 cm.
We know that the longer leg, which is across from the 60 degree angle, is equal to multiplying the shorter leg by 
.
Therefore, length of longer leg is approximately 01.04 cm.
75 degrees,
All triangles have a sum 180on the interior angles.
We know 90 and 30,
90+30=120,
180-120= 60.
60 is the measure of angle A.
Angle bisectors “cut an angle in half” per se, so 90/2=45.
45 is the measure of angle ACM
So, 60+45= 105,
180-105=75,
So the measure of the angle in question is 75.
Answer:
414.72 km
Step-by-step explanation:
formula: velocity= distance traveled by the time or v= d/t
velocity: 23.04 km/m
time: 18 min
distance: x
you have to change the formula a little bit
distance= velocity times time or d=v times t
23.04 times 18= 414.72
Answer:
Step-by-step explanation:
Perimeter is found by adding together all the lengths of the sides. For us, that is x + (2x + 5) + (6x - 17) + (3x + 2). Now we will just combine like terms. We can also drop the parenthesis because they do nothing for us and mean nothing to the problem.
x + 2x + 5 + 6x - 17 + 3x + 2 becomes
12x - 10
The answer for this equation is x=2
