Acarpenter is building a rectangular bookcase with diagonal braces across the back, as shown. the carpenter knows that mangle adc is a right angle and that mangle bdc is 35° greater than mangle adb. solve an equation to find mangle bdc and mangle adb.
what would the angle bdc measure to and what would the angle adb measure to?

using pemdas, (order of operations) you'll see the answer is 24.

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
