You need to use the angle sum of a triangle in triangle CAD to express y in term of x
for triangla CAD , y = (180 -x) /2
180 = 3x + [ (180-x)/2]
x = 36
hope this helps
Answer:
B
Step-by-step explanation:
12x3<u>></u> 35
Answer:
A. -4
Step-by-step explanation:
replace x with 2 in the function:
f(2) = 4×2 - 12 ➡ 8 - 12 = -4
Step-by-step explanation:
........
A) The larger and small triangles are similar, so
8/10 = x/15
x = (8*15)/10 = 12
b)find the altitude x
tan 40 = x / 5
x = 5 tan 40 = 4.195
By Pythagoras theorem:-
y = sqrt ( 4.195^2 + 11^2)
y = 11.8 to 3 significant figures
