Answer:
12/sin90'=b/sin67'
12sin67'=bsin90'
b=12sin67/sin90'
Step-by-step explanation:
sister ,we can use the law of sines. since we have the angle of elevation and assume the wall makes a right angle with the ground, our angle opposite the ground is 180-[90+23=67
hope this is helpful for you
Answer:
Last option.
Step-by-step explanation:
The consecutive exterior angle theorem states that the exterior angles are supplementary if two lines are cut by a transversal.
m∠1 + m∠7 = 180
m∠2 + m∠8 = 180
You have written exactly the same number twice, so neither of them is bigger.
Using proportions, considering the total number of students, it is found that 216 boys to linking their school lunch.
