Answer:
1: 7 2: 3
Step-by-step explanation:
The value of sin (pi/6) is 1/2
Answer:
150 meters
Step-by-step explanation:
Since 1 x 30 gives the 30
5 x 30= 150
Is 125 because u need to take the 5 and add 3 on the top
9514 1404 393
Answer:
x = 16
Step-by-step explanation:
Either or both of the right triangles can be used to find x. Or, triangle ABC could be used. All numbers are assumed to be degrees.
<u>Using ∆ABD</u>
55 +90 +2x+3 = 180
2x = 32 . . . . . . subtract 148
x = 16
<u>Using ∆BCD</u>
50 +90 +2x+8 = 180
2x = 32 . . . . . . subtract 148
x = 16
<u>Using ∆ABC</u>
55 +(2x +3) +50 +(2x +8) = 180
4x = 64 . . . . . . . subtract 116
x = 16
