Answer:

c) Right

Step-by-step explanation:

An Right triangle is a triangle with an angles being 90 degrees and we know that 2 of the angles are 59 and 31 and we know that the sum of all the angles in a triangle will equal 180 so 180-59-31 = 90 so this triangle has a 90 degree angle making it a right triangle

Which trigonometric identity is given by the formula adjacent side/opposite side?

Otrada [13]

Answer:

cot= adjacent side/opposite side

Option B is correct.

Step-by-step explanation:

We need to identify trigonometric identity which is given by the formula adjacent side/opposite side

The trigonometric identity for tan is

tan= opposite side/adjacent side

But We are given adjacent side/opposite side

Since cot is inverse of tan so, formula of cot is:

cot= adjacent side/opposite side

Option B is correct.

What is the approximate area of the shaded sector in the circle shown below?

Strike441 [17]

Answer:

Correct option is B.

Step-by-step explanation:

Given the radius of circle and the angle in sector we have to find the area of shaded region i.e minor sector.

$Radius=r=16 in.$

$Angle=\theta=110^{\circ}$

$Area of sector=}\frac{\theta}{360}\times\pi r^2$

$=\frac{110}{360}\times\frac{22}{7}\times(16)^2$

$=\frac{11}{36}\times \frac{22}{7}\times 16\times 16=245.841=246(approx.)$

∴ Area of sector is $246in^2$

Correct option is B.

Find the equation of the line passing through the points (2 11) and (-8 -19)

Svet_ta [14]

Answer:

Y=2x+7

Step-by-step explanation:

To find the gradient of the line u have to subtract the y intercepts and the x intercepts

11--9/2--8=20/10=2

Y-11/x-2=2

Y-11=2(x-2)

Y-11=2x-4

Y=2x-4+11

Y=2x+7
