Hello!
Here we have sin=opp/hyp so the sin of 45deg= 7/b so we have
Sqrt(2)/2 = 7/b so b= 7/sqrt(2)/2= 14/sqrt(2)= 14*sqrt(2)/2= 7*sqrt(2) so the final simplified answer for the value of b= 7*sqrt(2)
Any questions please ask. Thank you kindly.
Answer:
192 i think
Step-by-step explanation:
Your answer would be option B
Because multiplied by 4 the ratio would be 16:52
Find the ratio of the similar known sides:
1.34/2 = 0.67
The smaller triangle is 0.67 the size of the larger one.
Multiply the similar sides by the ratio:
DE = 4 x 0.67 = 2.68
FE = 3 x 0.67 = 2.01
