S4.13.t.71 Angles of triangle PQR

In summary, the sum of the angles in triangle PQR is always 180 degrees. To find the missing angle in triangle PQR, you can use the formula: Missing angle = 180 degrees - (angle P + angle Q). The angles of any triangle must be in degrees and cannot be in decimal form. Triangle PQR may or may not be a right triangle, as the angles can vary. The angles of triangle PQR are related to each other through the Triangle Angle Sum Theorem, which states that the sum of all three angles is always 180 degrees. This allows you to find the missing angle by subtracting the sum of the other two angles from 180 degrees.

232.q1.4a sketch the region of integration

$\displaystyle\int_{-2}^{2}\int_{\sqrt{4y^2}}^{4-y^2}
f(x,y)\,dx \,dy$

this is what i did with desmos don't know how
to shade the integrated area
if the it is even correct😎

Re: s4.13.t.71 angles of triangle PQR

sorry your correct
but there was a typo in the OP
it should of been
$\displaystyle\int_{-2}^{2}\int_{\sqrt{4-y^2}}^{4-y^2}
f(x,y)\,dx \,dy$

minus sign missing😰

how did you fill with red ... paint??

FAQ: S4.13.t.71 Angles of triangle PQR

What is the sum of the angles in triangle PQR?

The sum of the angles in any triangle is always 180 degrees. Therefore, the sum of the angles in triangle PQR is also 180 degrees.

How do you find the missing angle in triangle PQR?

To find the missing angle in triangle PQR, you can use the formula: Missing angle = 180 degrees - (angle P + angle Q). This works because the sum of all three angles in a triangle is always 180 degrees.

Can the angles of triangle PQR be in decimal form?

No, the angles of any triangle must be in degrees, which is a unit of angular measurement. Decimals are not used to measure angles.

Is triangle PQR always a right triangle?

No, the angles of triangle PQR can vary and it may or may not be a right triangle. A right triangle has one angle that measures 90 degrees.

How are the angles of triangle PQR related to each other?

The angles of triangle PQR are related to each other through the Triangle Angle Sum Theorem, which states that the sum of all three angles in a triangle is always 180 degrees. This means that if you know the measure of two angles, you can find the measure of the third angle by subtracting the sum of the other two angles from 180 degrees.
