B. obtuse
C. right
D. straight
3. m<RNY + m<GNC = 128 and <RNY is congruent to <GNC. What is m<RNY? (PLease HELP!)
congruent means they are equal
two equal angles add to 128,
so one of them is ?
64 degrees
looks good
To find the measure of <RNY, we can use the given information that m<RNY + m<GNC = 128 and <RNY is congruent to <GNC.
Since <RNY is congruent to <GNC, their measures are equal, so we can assign them the same variable, let's say x.
Now we can rewrite the equation as follows:
x + x = 128.
This simplifies to:
2x = 128.
To isolate x, divide both sides of the equation by 2:
2x/2 = 128/2,
x = 64.
Therefore, the measure of <RNY is 64 degrees.
