Answer : acute
Right triangle : a^2+b^2=c^2
Acute triangle : a^2+b^2 > c^2
Obtuse triangle:a^2+b^2 < c^2
6^2+7^2 > 9^2
X + y = 14
x = 3y + 2
3y + 2 + y = 14
4y + 2 = 14
4y = 14 - 2
4y = 12
y = 12/4
y = 3 <===
x = 3y + 2
x = 3(3) + 2
x = 9 + 2
x = 11 <===
25/5
Step-by-step explanation:
first make the coefficient of x alone... So that you should take the 4 out... then you get 4times x squared + 5x then you should didvide the x term by 2(always) and then you get 5/2...So then the third term or the constant is tye square of that..
True
<span>Cos(A+B)=CosACosB-SinASinB
therefore Cos(A+A)= CosACosA - SinASinA
= Cos^2A - Sin^2A</span>
