Answer:
2, 5 // b, e
Step-by-step explanation:
Answer:
x = 1
y = 1.7
z = 60⁰
work:
z = 60 because the three angles add to 180⁰ and 180⁰ - 90⁰ - 30⁰ = 60⁰
in a 30-60-90 triangle, the hypotenuse is twice the length of the shorter leg, so x = 1.
the longer leg is the short leg * Sq rt of 3
Sq rt of 3 to the nearest tenth is 1.7, so 1.7 * 1 is still 1.7, so y = 1.7.
Using exterior angle formula, you get that ∠CAD=36+123=159°
Exterior angle formula says that the angles facing CAB (ACB and ABC) sum to CAD.
Answer:
its a 65 degree angle
