So what you want to do is multiply 245 by 1.65 (because it’s +65%) and by doing that you get $404.25 :)
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.

Answer:
The length of AB is 7.45 units.
Step-by-step explanation:
You can find the length of AB using Cosine Rule, cosθ = adj./hypo. :
θ = 20°
adj. = 7 units
hypo. = AB
cos 20° = 7/AB
AB = 7/cos 20°
= 7.45 units (3s.f)
The last choice because anything greater than a negative number eventually leads to the posetive numbers, plus substituting any posetive number aolves the inequality.
