Step-by-step explanation:

$\angle 1$ is the exterior angle of the given $\triangle.$

Therefore, by remote exterior angle theorem.

$\therefore \: m \angle \: 1 = 60 \degree + 63\degree \\ \\ \huge \red{ \boxed{\therefore \: m \angle \: 1 = 123 \degree }}$

In ΔOPQ, q = 110 inches, o = 970 inches and ∠P=167°. Find the area of ΔOPQ, to the nearest square inch.

ki77a [65]

Answer:

$Area = 12004$ square inches

Step-by-step explanation:

Given

$q = 110$

$o = 970$

$\angle P =167$

Required

The area of the triangle

To do this, we use:

$Area = \frac{1}{2} * o * q * sin(P)$

So, we have:

$Area = \frac{1}{2} * 970 * 110 * sin(167^\circ)$

$Area = \frac{1}{2} * 970 * 110 * 0.2250$

$Area = 12003.75$

Approximate

$Area = 12004$

What is the equation of a circle with center (2,-3) and radius 3?

Ierofanga [76]

Answer:

(x-2)²+(y+3)²=9

Step-by-step explanation:

We know that the formula for the area of the circle is:

(x-h)²+(y-k)²=r²

-h,k being the center coordinates

-r being the radius

In this case, (2,-3) are the center coordinates and 3 the radius, so simply plug these into the equation giving us:

(x-2)²+(y+3)²=9
