Answer:
y = 75
Step-by-step explanation:
The sum of the angles in a quadrilateral = 360°
∠DGF and 80° form a straight angle and are supplementary, hence
∠DGF = 180° - 80° = 100°
Subtract the sum of the 3 angles from 360 for the value of y
y = 360 - (65 + 120 + 100) = 360 - 285 = 75
Answer:
SI=P ×R × T
Step-by-step explanation:
P=$500
R=6%
T=3 years
SI=500×3×6 ÷100
=$90
Answer:
The measure of each angle:
152.8° and 27.2°
Step-by-step explanation:
Supplementary angles sum 180°
then:
a + b = 180°
a - b = 125.6°
then:
a = 180 - b
a = 125.6 + b
180 - b = 125.6 + b
180 - 125.6 = b + b
54.4 = 2b
b = 54.4/2
b = 27.2°
a = 180 - b
a = 180 - 27.2
a = 152.8°
Check:
152.8 + 27.2 = 180°
Answer:
LCD = 2(3)(5)(7)(x)(x) is A
LCD = (x - 3)(x + 1) is D
LCD = (x + 2)(x - 3) is C
LCD = 2(3)(5)(7)(x) is B
