8. complementary angles = 90°
3x+3+10x-4 = 90
13x-1 = 90
13x = 91
so x = 91/13= 7
then K = 3(7)+3 = 24°
so L = 10(7)-4 = 70-4 = 66°
9. P is three less than twice of Q
so P = 2Q-3
supplementary angles = 180°
P+Q = 180
(2Q-3)+Q = 180
3Q-3 = 180
3Q = 183
so Q = 183/3 = 61°
then P= 2(61)-3 = 122-3 = 119°
10. B is two more than three times of C so B= 3C+2
complementary angles = 90°
B+C= 90
(3C+2)+C=90
4C+2=90
4C= 88
so C= 22°
then B = 3(22)+2= 66+2 = 68°
Answer:
to survive
Step-by-step explanation:
if you don't eat you are gonna died➡
Answer: No.
Step-by-step explanation: This is not a right triangle because if you add up all the sides, it does not equal 90 degrees.
90 degrees because you can see at the part that is in the middle it is 90 degrees
Answer:
y = 15
Step-by-step explanation:
24 = 8/5y
y = 24/8/5
y = 120/8
y = 15
