Question 1. enter the ratio equivalent to sin(b)

question 2. consider this a right triangle. enter the measure of angle cab to the nearest hundredth degree.

question 3. suppose angle a is an angle such that angle cosa < sina. select all angle measures that are possible values for angle a. 25, 35, 45, 55, 66, 75.

The three questions about the given triangle has been answered below.

Step-by-step explanation:

We are given a right angled triangle whose sides are of length 20, 21 and 29.

(1) sin(B) =

              =

              = 0.72

(2) sin(A) =

     sin(A)  = 0.689

     ∠CAB =

     ∠CAB = 43.551°

(3) We suppose that cosA < sinA and we haveto find which all angles will satisfy this condition.For this the angle A should be greater than 45°.

From the given options the angles that satisfy this are 55 , 66 and 75.

45 is not included as then sinA = cosA and that condition is not there.

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
