Question 1170965


∠JKL and ∠RST are complementary. 

m∠JKL = 36° and m∠RST = ( x + 15)°. 
Find the value of x and the measure of ∠RST . 
complementary angles are two angles whose sum is 90°
{{{36+x + 15=90}}}°
{{{51+x =90}}}°
{{{x =90-51}}}°
{{{x =39}}}°

->the measure of ∠RST== ( 39 + 15)=54°



4. ∠SUN and ∠CAT are supplementary. 
supplementary angles are two angles whose sum is180°

m∠SUN = (2x)° and m∠CAT = 142°. 

{{{2x+142=180}}}
{{{2x=180-142}}}
{{{2x=38}}}
{{{x=19}}}

m∠SUN = (2*19)=38° 



 5. ∠P and ∠Q are supplementary.
