Find the measures of the angles of a right triangle with the legs measuring 4 and 7.
explain good for brainliest.

answer:

90, 29.75 and 60.25

step-by-step explanation:

assuming you are familiar with the sohcahtoa mnemonic, you can find one of the angles using the toa part, ie.:

so the angle

knowing that it is a right triangle, so one angle is 90° and the angles should add up to 180°, the other angle must be 180-90-29.75 = 60.25

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
