Answer:
If TriangleABD is a right angled triange X=31°
y= 3
Step-by-step 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
Answer:
Step-by-step 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.
