Answer:
Area of the triangle WXY = 365.3 mm²
Step-by-step explanation:
By applying Sine rule in the given triangle XYW,
![\frac{\text{SinY}}{\text{WX}}=\frac{\text{SinX}}{\text{YW}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BSinY%7D%7D%7B%5Ctext%7BWX%7D%7D%3D%5Cfrac%7B%5Ctext%7BSinX%7D%7D%7B%5Ctext%7BYW%7D%7D)
![\frac{\text{Sin70}}{\text{WX}}=\frac{\text{Sin43}}{\text{24}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BSin70%7D%7D%7B%5Ctext%7BWX%7D%7D%3D%5Cfrac%7B%5Ctext%7BSin43%7D%7D%7B%5Ctext%7B24%7D%7D)
WX = ![\frac{24.\text{Sin70}}{\text{Sin43}}](https://tex.z-dn.net/?f=%5Cfrac%7B24.%5Ctext%7BSin70%7D%7D%7B%5Ctext%7BSin43%7D%7D)
= 33.068 mm
= 33.07 mm
Area of a triangle = ![\frac{1}{2}a.b.\text{Sin}\theta](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Da.b.%5Ctext%7BSin%7D%5Ctheta)
where a and b are the sides of the triangle and θ is the angle between the sides a and b.
Area = ![\frac{1}{2}(33.07)(24)\text{SinW}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%2833.07%29%2824%29%5Ctext%7BSinW%7D)
Since, m∠X + m∠Y + m∠W = 180°
m∠W = 180 - (43 + 70)
= 67°
Area of the triangle WXY = ![12\times (33.07)\text{Sin67}](https://tex.z-dn.net/?f=12%5Ctimes%20%2833.07%29%5Ctext%7BSin67%7D)
= 365.29 mm²
≈ 365.3mm²
It equals -1. Anytime you multiply a negative by a positive it becomes a negative. If you multiply to negatives it becomes a positive. And two positives multiplied makes a positive.
Answer:
I got 17.
Step-by-step explanation:
Because it takes 4 days to make 20 small frames, it takes 8 days to make 40. And because it takes 3 days to make 21 frames, and 21 multiplied by 3 is 63 (one less than 64), it would take 9 days (3 times the amount for 21) to make 64 large frames. In all, it would take APPROXIMATELY 17 days (9 +8 is 17)
Answer:
\[a_{n}=6n-4\]
Step-by-step explanation:
a8=a1+(8-1)*6
44=a1+42
a1=44-42=2
\[a_{n}=2+(n-1)*6\]
\[a_{n}=6 n-4\]
