Hi, can I have some help with this question please ?

x = 67.5 degrees

Step-by-step explanation:

A circles' angles add upto 360 degrees and one of the angle is 90 degrees.

=> x+3x+90 = 360 degrees

=> 4x+90 = 360

=> 4x = 360-90

=> 4x = 270

Dividing both sides by 4

=> x = 67.5 degrees

So, the measure of <x is 67.5 degrees.

Solution,

( sum of complete turn)

Subtract 90 on both sides:

Divide both sides by 4

Hope this helps...

Good luck on your assignment...

2 2/3 hours duhh silly

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
