You graph the y-intercept first... The y-intercept is -4 so you go down four units on the y-axis that will be your first point (0,-4). The slope is 3/4 and can be translated as rise over run. rise is numerator run is denominator. From the -4 You rise three units up since its positive three, and then you run 4 units to the right since the 4 is positive. Your second point should be at (4,-1).
Answer: h = 14.5 ft
Step-by-step explanation: Since it is given angles and side and it wants a side, let's use <u>Law</u> <u>of</u> <u>Sines</u>, which is formulated as
![\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}](https://tex.z-dn.net/?f=%5Cfrac%7BsinA%7D%7Ba%7D%20%3D%5Cfrac%7BsinB%7D%7Bb%7D%20%3D%5Cfrac%7BsinC%7D%7Bc%7D)
i.e., the ratio of a side and the sin of its opposite angle is constant.
So, for this triangle, height is
![\frac{sin46}{h} =\frac{sin44}{14}](https://tex.z-dn.net/?f=%5Cfrac%7Bsin46%7D%7Bh%7D%20%3D%5Cfrac%7Bsin44%7D%7B14%7D)
![h=\frac{14sin46}{sin44}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B14sin46%7D%7Bsin44%7D)
![h=\frac{10.07}{0.69}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B10.07%7D%7B0.69%7D)
h = 14.51
Height of the main sail rounded to the nearest tenth is 14.5 ft.
Triangle BCD and triangle EFG are similar right triangles
Side corresponds to side BD is EG
Answer
EG
B. and c.
each pair has an opposite angle made by an intersecting line
Answer:
-4 = y
Step-by-step explanation:
3(6+5y)=2(-5+4y)
18 + 15y = -10 + 8y
+10 +10
28 + 15y = 8y
- 15y -15y
28 = - 7y
28/-7 = -4
-7y/-7 = y
