I found it! It's 52 degrees.
A central angle of 120 is 1/3 of the total circle. Aea of a circle = pi x r2, so for this sector the area is (1/3)pi x r2 = (1/3)(3.14)(52) = 26.17
A ratio is a comparison of two numbers. You can write a ratio in these ways: a to b, a : b, or a/b. Ratios are often written as fractions. A ratio that is expressed as a fraction is generally written in lowest terms. If the ratio involves unit of measure, you must ensure that the units are the same. Example: Write ratios in lowest terms. 20/52 = (20/4)/(52/4) = 5/13 240/200 = (240/40)/(200/40) = 6/5 There are continued ratio, or extended ratio, which relates more than two numbers. Example: The measures of the angles of a triangle are related by the ratio 3 : 4 : 5. Find the measure of each angle. Solution: The ratio 3 : 4 : 5 is equivalent to 3x + 4x + 5x. We write an equation by using, 3x, 4x, and 5x to represent the measures of the angles. The sum of the angles of a triangle is 180 degrees. So, 3x + 4x + 5x = 180 12x = 180 x = 15 Thus, the measures of the angles are 45 degrees, 60 degrees, and 75 degrees.
It is an obtuse scalene triangle.
Answer: first angle =52 degree, second angle = 128 degree. Solution: x+y=180 (1) x+y/4=84 now multiply both sides of last equation by 4: 4x+y=336 (2) subtract (1) from (2), ie. find (2) - (1): 4x-x + y-y = 336-180 3x=156 dividing last result by 3: 3x/3=156/3 x=52 substitue in eq. (1): 52+y=180 y=180-52=128
It is 128 degrees because 128+52 = 180 degrees
An angle and its complement sum to ninety degrees. 90-52=38
128 degrees.An angle's supplement, when added to the original angle, will form a straight (180 degree) angle.
The supplement of an angle is the angle that, when added to the original angle, equals 180 degrees. The complement of an angle is the angle that, when added to the original angle, equals 90 degrees. Therefore, the supplement of the complement of a 38-degree angle would be the angle that, when added to the complement of 38 degrees (52 degrees), equals 180 degrees. This angle would be 128 degrees.
The third angle is (128 degrees) minus (the second angle).
26 degrees
An angle of 52 degrees, as with any angle between 1 and 89 degrees, is an acute angle.
Angle and its complement have a sum of 90 degrees: A+C = 90 Angle plus five times its complement is 298 degrees: A+5C = 298 Subtract first equation from the second: 4C = 208 C = 52 So, the complement is 52 degrees and the angle is 38 degrees
It works out that the other two angles are 29 degrees and 52 degrees. Check: 29+52+99 = 180 degrees
The complement: 38° (90-52=38) The supplement: 128° (180-52=128)
All triangle angles add to 180 degrees. Since one is 38 and the right angle is 90, the third angle is 180 -38-90 = 52 degrees
It is: 90-52 = 38 degrees
