A quadrilateral has two angles that measure 238° and 100°. The other two angles are in a ratio of 5:6. What are the measures of those two angles?

10 degrees and 12 degrees

Step-by-step explanation:

The first step is to establish the measure of the sum of the other two degrees and since the sum of all angles in a quadrilateral is 360 degrees we find:

360-238-100=22 and since the ratio of the two angles is 5:6 we can split 22 into 5 and 6 pieces of equal measure (their measure will be represented as x) to find: 5x+6x=22; 11x=22; x=2

And to find the measures: Measure of angle one (the smaller angle) is 5*2=10

Measure of angle two (the larger angle): 6*2=12

And to check the answer check that:

10/12=5/6 (checking the ratio); 10+12+238+100=360 (checking if it is a quadrilateral)

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
