What is the measure of angle A?
I am Lyosha [343]

First you have to find the angle B (check attachment)

B = 180^{\circ} - 137^{\circ} = 43^{\circ}\\

Then you can find the last angle inside the triangle, which I'll call C

C = 180^{\circ} - 102^{\circ} - 43^{\circ} = 35^{\circ}

Now you can find angle A

A = 180^{\circ} - C = 180^{\circ} - 35^{\circ} = 145^{\circ}

PLEASE HELP!! What is the value of x?
Black_prince [1.1K]
To find x, first we'll split the triangle in two right triangles.

The first triangle will be the one with sides (8,x+4,y) and the second triangle will be the one with sides (12,2x+1,y).

As you can see, these two triangles share the side 'y'.

To solve we'll do the following; first solve for 'y' by applying the Pythagorean theorem in the second triangle, and finally solve for 'x' applying Pythagorean theorem in the first triangle.

From the second triangle (12,2x+1,y) we solve for 'y' by writing:
y^{2}=12^{2}- (2x+1)^{2}=144-4 x^{2} -4x-1=

Now that we know 'y^2' we apply Pythagorean Theorem in the first triangle (8,x+4,y)
8^{2}= (x+4)^{2}+ y^{2}= (x^{2}+8x+16)+(143-4 x^{2} -4x)
64=159-3 x^{2} +4x

Now you solve the quadratic equation, you'll get a positive and negative value; as this are lengths, you take the positive and get:

x= \frac{19}{3}
