Answer:
$2.48
Step-by-step explanation:
29.75/12 =2.479
The set of lengths that could not form a triangle is 15,7,6
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
3x - 18 + 105 = 180
3x + 87 = 180
3x = 180 - 87
3x = 93
x = 93/3
x = 31 <==
Answer:
so this is really simpel x=1 thats it
Step-by-step explanation:\sin ^2\left(20^{\circ \:}\right)\left(x\right)+\cos ^2\left(20^{\circ \:}\right)\left(x\right)=1 \sin ^2\left(20^{\circ \:}\right)x+\cos ^2\left(20^{\circ \:}\right)x=1
