What complementary angle to a 70 degrees angle has a measure of?

Complementary angles add to 90 degrees so the complementary angle to 70 degrees has a measure of 20 deg.


What angle is complementary to 70 degrees?

Complementary angles are angles that add up to 90 degrees. So, the complementary angle of 70 degrees would be 20 degrees


When angles are complementary the sum of their measures is 90 degrees two complementary angles have measures 2X -10 and 3X -10 find the measures of each angle?

2x-10+3x-10=90 5x-20=90 5x=110 x=22


Two angles are complementary If the measure of one angle is 20 more than the measure of the second angle what is the number of degrees in the measure of the smaller angle?

first you have to change this into equation by "translating" it into math. so let x= the first angle 90-x ( because complementary means they add up to 90) = the second angle x= (90-x) + 20 x+x = 90-x+20+x 2x = 90-20 2x = 70 x = 35 the smaller angle = 35 degrees


If one angle is 10 more than 3 times as large as another angle which is complementary to it what is the measure of the smaller angle?

The smaller angle is 20 degrees and the larger is 70 degrees. Complementary angles total 90 degrees. Let's call the smaller angle A. The other angle is 3A + 10. The sum of both angles is 90, so 4A +10 = 90, 4A = 80, A = 20. The larger angle is 3(20) + 10 = 70.


Three angles are complementary The ratio of their measures is 235 Find the measure of each angle?

Assuming you meant ratio is 2:3:5 then: A: Since the angles have this ratio, we can express their measures as 2x, 3x, and 5x for some value x. Since the angles are complimentary, their sum must be 90 degrees (pi/2 radians). This means that: 2x+3x+5x = 90 (pi/2) 10x = 90 (pi/2) x = 9 (pi/20) So the angles have measure: 18, 27, 45 degrees or pi/10, 3pi/20, and pi/4 radians


How do find the angle measure for a 20 gon?

first you have to find the sum of angles and sides. then subtract 2 which is 18 and multiply 18 times 180.


What is the measure of each angle of an isosceles triangle if the measure of the third angle is 7 times the measure of either of the two base angles?

The angles are 140 degrees, 20 degrees and 20 degrees that add up to 180 degrees


How do you find the measure of each exterior angle of a regular 20-gon?

The exterior angles add up to 360 degrees. So: 360/20 = 18 degrees


What angles have measures that add up to 90 degrees?

The Answer:30, and 60, or 37, 33, 20 are some examples. These angles are considered "complementary angles". There are 56634173 partitions (with integer values and including 90 itself) for 90.


What is the sum of the measure in degrees of the interior angles of a 20-sided polygon?

3240o


What is the sum of measure in degrees of the interior angles of the interior angles of 20- side polygon?

For any polygon of N sides, the sum of the interior angles (in degrees) is 180*N-360, which for N=20 is 3240°
