Answer:
4a)= 2.1m 4b)= 1.9 m 5)= 29.6º
Step-by-step explanation:
4a):
x is the opp
AB is the hyp
BC is the adj
thus,
sin32 = x/4
cross multiply, x= 4*sin32
x= 2.1196.......
x=2.1 m
4b).
x is the hyp
ac is the opp
bc is the adj
thus,
cos65=4.5/x
cross multiply, x= 4.5*cos65
x=1.9017....
x=1.9 m
5).
AB is the opp
bc is the adj
ac is the hyp
thus:
tanC= 2.1/3.7
C= tan^-1 (2.1/3.7)
C= 29.5778.....
C= 29.6º
Y+5 can be written to find the value of y by combining like terms .
Answer:
Step-by-step explanation:
We assume the given sum is the sum of interior angles of a triangle, so is equal to 180°.
48° +X +(X -44°) = 180°
2X +4° = 180° . . . . . . . . . . collect terms
X +2° = 90° . . . . . . . . . . . .divide by 2
X = 88° . . . . . . . . . . . . . . . subtract 2°
Then the other interior angle is ...
(X -44°) = 88° -44° = 44°
The unknown interior angles are ...

Step-by-step explanation:
Mean vs Median
The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set: 10 + 10 + 20 + 40 + 70 / 5 = 30.
The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.
