Answer:
D
Step-by-step explanation:
4x^4+3x^2-3x^3-3x+1
Hence they are similar
#2
- <A=<H
- And ratio of sides are same
Hence both triangles are similar by SAS property
#3
Answer:
B
Step-by-step explanation:
using the tangent ratio on the triangle on the right and the exact value
tan60° = , then letting the altitude be h
tan60° = = = ( multiply both sides by h )
11 = h × ( divide both sides by )
11 = h
using the sine ratio in the triangle on the left and the exact value
sin45° = , then
sin45° = = = = ( cross- multiply )
× x = 22 ( divide both sides by )
x = 22
