Answer:

m∠C = 30°

Step-by-step explanation:

If ΔADB is an equilateral, then m∠A = m∠ADB = m∠DBA = 60°

If ΔDBC isosceles with DB ≅ BC, then m∠C = m∠BDC ;

m∠C + m∠BDC = m∠DBA = 60° ⇒ m∠C = 30°

1.) What is the solution to the system of equations below? y = 2x + 8 3(-2x + y) = 19

-BARSIC- [3]

Answer:

y = 2x + 8

6x + 3y = 19

6x + 3(2x + 8) = 19

6x + 6x + 24 = 19

12x = -5

x = -5/12

y = 2(-5/12) + 8

y = -5/6 + 48/6

y = 43/6

Question 1. Enter the ratio equivalent to sin(B)

Deffense [45]

Answer:

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) = $\frac{side opposite to B}{hypotenuse}$

= $\frac{21}{29}$

= 0.72

(2) sin(A) = $\frac{20}{29}$

sin(A) = 0.689

∠CAB = $sin^{-1}(0.689)$

∠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.
