cos-1(0.74) = 42.26858443 degrees
The equation 7 times 42 is equal to 294.
cos(42o) = 0.7431448255 ==============( approximately 37/50 )
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
42 degrees Celsius = 107.6 degrees Fahrenheit
The supplementary angle to 42 degrees is 138 degrees
The equation 7 times 42 is equal to 294.
To convert Fahrenheit to Celsius: subtract 32 from the Fahrenheit temperature, multiply the answer by 5, then divide this by 9. The answer will be the Celsius temperature. 42° F = (42 - 32) x 5 ¸ 9° C = 50 ¸ 9° C = 5.556° C
42º Celsius = 107.6 Fahrenheit = 315.15º Kelvin
cos(42o) = 0.7431448255 ==============( approximately 37/50 )
If you are dealing with an isosceles triangle, if one of the base angles measures 42 degrees then the other base angle measures 42 degrees. (By definitioin an isosceles triangle has at least 2 equal sides and the angle opposite those sides with be equal.) If you add up the degrees in each angle within a triangle, it will always equal 180 degrees. Knowing all this you can set up a formula: Angle 1 + Angle 2 + Angle 3 = 180 42 + 42 + Angle 3 = 180 Angle 3 = 96 degrees

90 degrees - 42 degrees = 48 degrees
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
42 degrees Celsius = 107.6 degrees Fahrenheit
The supplementary angle to 42 degrees is 138 degrees
42 degrees Celsius in Fahrenheit is about 107.6 degrees.
This can be written as 16 + x = 42. We know that x, or your "something" is exactly 16 less than 42. All you would have to do to solve it would be to subtract 16 from 42. 42-16=26 so your x value is 26.
