Answer:
109.5; B
Step-by-step explanation:
From your identity,
CosA = adjacent/ hypothenus
A represent an arbitrary angle between the sides in question.
In the question above, A=64
Hypothenus is the longest side and adjacent is the side just below the angle .
In the above case,
Hypothenus= X
adjacent =48
This means;
Cos64 = 48 /X
X = 48 / cos64; [ from cross multiplication and diving through by cos64]
X = 48 /0.4383 [ cos64 in radian = 0.4383]
= 109.51
= 109.5 to the nearest tenth.
Note( do your calculation of angle in radian or else, you won't get the answer)
Answer:
x=3
Step-by-step explanation:
Right triangle so you can use pythagorean theorem
a squared + b squared = c squared
b=x
14^2 + b^2= 17^2
14+b=17
b=3
It is 4.............4.............4
Answer:
1 3/4
Step-by-step explanation:
3 1/2 boxes of tomatoes currently. uses 1 3/4, taking it away basically.
3 1/2 - 1 3/4
3 2/4 - 1 3/4 ;; i did this with finding a common denominator for it to be easier for me to solve.
3 - 1 = 2
2/4 - 3/4 = -1/4
2 + -1/4 = 1 3/4
correct me if wrong.
