Answer:
1 = 52°
2=79°
3= 38°
Step-by-step explanation:
each triangle equals 180°
and 1 and 3 also make a right angle which should always be 90°
Well, yeah, sometimes we have that weird feeling that our guts know the answer but we don't know why. Let me show you how I got mine.
Gravitational force obeys an inverse square law - as in the gravitational force depends on the distance as<span>F = <span><span>GMm/</span><span>r</span></span></span>²
Small m is the mass of astronaut, M the planet, etc. equate the two forces to have the astronaut in equilibrium. G, m cancel, then arrange to get the Mass ratio:<span><span><span><span>Mx / </span><span>My</span></span> =<span><span>140</span></span></span></span>²/581²
Answer:
72 cm
Step-by-step explanation:
It would be multiplied by 8 so the length would become 72 cm
In order to be parallel to a line, two lines must have the same slope. The slope of y=3x+2 is 3. So the slope of the other equation has the be 3. y=3x+b. Now we can plug in the x and y values given by the point to calculate the b in the equation.
-3=3(-1)+b
-3=-3+b
b=0
So the equation is y=3x
Ok so if they are similar that means equal angles so 50+70=120 then 180-120=60 so the answer is A. <span>#TeamAlvaxic</span>
