Answer:
11.)4.79mi
12.)8cm
13.)10.6km
14.)5.93
15.)2yd
16.)5.41in
17)2y
18)2m
19)11.8yd
20)4.51km
Step-by-step explanation:
11.)15.8x2=31.6 31.6/6.6=4.79
12.)64/8=8
13.)26x2=54 54/4.9=10.6
14.)8.6x2=17.2 17.2/5.93
15.)2/1=2
16.)29.2/5.4=5.41
17)4/2=2
18)10/5=2
19)139.2/11.8=11.8
20)20.3/4.5=4.51
A square has all sides of the same length. This means that the length and width are both 14 miles. The area of a square is Length times width, or 14 times 14. This comes out to be 196 miles squared
Answer:
<em><u>Yes I Agree And Wanna Zoom?</u></em>
Part 1) <span>In triangle PQR, mP= 43, PQ=7.5 and PR= 8.4. What is mR to the nearest degree?
we know that
the law of cosines establishes that
c</span>²=a²+b²-2*a*b*cos C
in this problem
c=QR
a=PQ=7.5
b=PR=8.4
C=angle P=43°
c²=a²+b²-2*a*b*cos C----> c²=7.5²+8.4²-2*7.5*8.4*cos 43°
c²=34.66--------> c=5.89
QR=5.9
applying the law of sines
7.5/sin R=5.9/sin 43-----> 7.5*sin 43=5.9*sin R---> sin R=7.5*sin 43/5.9
sin R=0.8669---------> R=arc sin (0.8669)----> R=60.11°----> R=60°
the answer Part 1) is the option
<span>D. 60
</span>
Part 2) <span>In triangle ABC mA=43, mB=62 and BC=22 in. What is AB to the nearest tenth of an inch?
we know that
</span>∠C=180-(62+43)-----> ∠C=75°
<span>
Applying the law of sines
22/sin 43=AB/sin 75------> AB=22*sin 75/ sin 43-----> AB=31.16 in
AB=31.2 in
the answer Part 2) is
</span><span>D.31.2</span>
