Answer:
Step-by-step explanation:
take 56 degree as reference angle
using sin rule
sin 56=opposite/hypotenuse
0.82=AB/15
15*0.82=AB
12.3=AB
-7 + 4x - 5x^2 + 3x^3....ascending means smallest to largest
Since we know a triangle only has 180 degrees we can say:
99+3x+x+5=180
Then we can solve for x:
4x+104=180
4x=76
x=19
Answer:
0.6
Step-by-step explanation:
2×3x+4+4=12
6X+8=12
6x=12-8
6x=4
Divide by 6
X=0.6
Answer:
60 degrees
Step-by-step explanation:
EF and DC have lines through them indicating that they are equal in length, telling us that the figure is an isosceles trapezoid. Congruent base angles are a property of isosceles trapezoids, like isosceles triangles. This means that the base angles C and F will have the same measure. The measure of angle F is 60 degrees, therefore the measure of angle C will also be 60 degrees.
hope this helps :)
