Step-by-step explanation:
(5)
Since Δ JKL is isosceles then the base angles are congruent, that is
∠ LJK = ∠ LJG = 80° , thus
∠ JLK = 180 - (80 + 80) = 180 - 160 = 20
x = 20 ÷ 2 = 10
(6)
Since Δ PQR is equilateral, then each of its angles = 60°
∠QRS = 60° - 32° = 28°
Since Δ SQR is isosceles then base angles are congruent, then
∠ SQR = ∠ QRS = 28 , thus
x = 180 - (28 + 28) = 180 - 56 = 124
Answer:
he bought 20 CDs
Step-by step
25(1.80) equals 45
69-45= 24
24 divided by 1.20 equals 20
Answer:
9x ≤ -37
Step-by-step explanation:
A product of a constant and a variable is indicted by writing the constant next to (typically, in front of) the variable. The symbol ≤ means "is less than or equal to". So ...
(the product of 9 and x) (is less than or equal to) -37
9x ≤ -37
