Let's apply the law of sine to calculate angle C
sin(81)/26 = sin(C)/28
0.1646 = sin(C)/28 and sin(C) =1.063. Sine sin(α) cannot be > than 1, so this triangle is invalid
Answer:
Correct to 1dp
127.3 cm = 127.0 cm
86.5 cm = 87.0 cm
Upper limits:
127.0 cm = 127.05 cm
87.0 cm = 87.05 cm
Lower Limits:
127.0 cm = 126.95 cm
87.0 cm = 86.95 cm
upper limit of perimeter of rectangle:
P = 2(l+w)
= 2(127.05 + 87.05)
= 2(214.1)
= 428.2 cm
lower limit of perimeter of rectangle:
P = 2(l+w)
= 2(126.95 + 86.95)
= 2(213.9)
= 427.8 cm
therefore;
<h2><u>ANSWER </u></h2>
x= 3
Step-by-step explanation:
=> -4x – 5 + 2x = -11
=> -2x = -11+5
=> -2x = -6
=> x= 6/2
=> x= 3
If you multiply 36 by four since there are 4 wheels for skateboard
you will get 144. That number is the total number of wheels you need to order and since they come in packs of 20 what you need to do is divide 144 by 20 and you will get 7.2. So obviously you can't order 7.20 packs of wheels so this means that 8 packs of wheels must be bought in order to ensure that all of the skateboards get wheels on them.
The answer is 8.
Answer:
The two possible cases are
(i) the base angles are each 40° and the vertex angle is 100°,
(ii) the base angles are each 70° and the vertex angle is 40°.
