Y-5=3(x+1)
y-5=3x+3
add 5 to both sides
the answer would be y=3x+8
Answer:
Y = 59.0°
Step-by-step explanation:
Using the cosine rule in terms of x, y and z
cosY =
with x = 22, y = 20 and z = 18
cosY =
=
= , thus
Y = ( ) ≈ 59.0° ( to the nearest tenth )
Answer: This triangle is <u>not</u> a right triangle
Step-by-step explanation:
In a right triangle, the hypotenuse(c) is always the longest side and a and b are the shorter sides. Thus, 5^2+9^2=13^2. Simplify this to get 25+81=169, then 106=169. Because 106 does <u>not</u> equal 169, it is not a right triangle.
