Question

I really need help with this please! It’s due tonight.

Answer 1

Explanation:

x+59=90 because the right angle adds up to 90 degrees.

x+59-59=90-59

x+0=31

x=31 degrees

y=3cm because the sides of a triangle are equal.

Answer 2

If TriangleABD is a right angled triange X=31°

y= 3

Explanation:

A = C = 59° ( Angles opposite equal sides are equal)

therefore if ABD is a right angled triangle also CBD will be a right angled triangle and then add the angles and equal them to 180

B+C+D=180

59+x+90=180

x=31°

For you can use trigonometric ratio which is tanx=y/DB but first lets look for DB , from triangle ABD we can use tan59=DB/3 : . DB= 4.99 or 5

then tanx=y/5

tan31=y/5

y=3 units
