Find the measure of angle y. round your answer to the nearest hundredth. ( type the numerical answer only) a right triangle is shown with one leg measuring 7 and the hypotenuse is labeled 12. an angle that is not 90 degrees is marked y.

the measure of angle y is 36°

step-by-step explanation:

for better understanding of the solution, see the attached figure of the problem :

given that : δabc is a right angled triangle. ab = 7 units , ac = 12 units

to find : measure of ∠acb which is marked as y

solution :

since, δabc is a right angled triangle, so using sine rule in the triangle

therefore, the measure of angle y is 36°

the value of y is 36°.

step-by-step explanation:

  in figure,

using trigonometric ratio

siny =

siny   =

y =

y= 35.68° (approx)

thus, the value of y is 36°.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
