Answer:
<u>Given</u>
- ΔTQR is right
- QS is altitude
- ΔRSQ and ΔTSQ also right
- m∠TQS = 42°, RS = 26 cm
∠RQS and ∠TQS are complementary with ∠TQS, so are 48°
a)
- ∠QRS is the another one with 42°
b)
<u>Find QS first</u>
- 26/QS = tan 48°
- QS = 26 / tan 48° = 23.4
<u>Find QT next</u>
- QS/QT = cos 42°
- QT = QS / cos 42° = 23.4 / cos 42° = 31.5 (rounded)
Answer: Your bones
Step-by-step explanation: Since your "skeletal system" here is your bones, it helps you walking and running. They move back and fourth along with muscles to help you walk.
Answer:
10. X=3
11. FG=15
12. QS=34
Hope this helps
Step-by-step explanation:
10. 8x+11=12x-1
8x-12x=-1-11
-4x=-12
x=3
11. 11x-7=3x+9
11x-7=-9+7
8x=16
x=2
Substitute the (x)
11(2)-7 =15
12. 5x-3=21-x
5x+x=21+3
6x=24
x=4
Substitute the (x)a
5(4)-3=17
21-(4)=17
17+17=34
