Answer:

1) x=30 degrees

2)y=20 degrees

1) 3x+2x+1x= 6x (a triangle is normally 180 degrees) 180 divide 6=30 (this is because 6 Xs make up the triangle)

2) 2y+5y+5+y+15= 8y+20, (since a triangle has 180 degrees) 8y+20=180 (-20 from both sides) 8y=160, 160 divide 8=20

(I hope this makes sense)

Write a rule to describe the function shown.

I am Lyosha [343]

Answer:

y = -3x

Step-by-step explanation:

(a) Slope

y = mx + b

Choose points (-3, 9) and (3, -9)

m = (-9 - 9)/(3 – (-3))

m = -18/(3 + 3)

m = -18/6

m = -3

=====

(b) y-intercept

y = mx +b

Choose point (0,0).

0 = 0 + b

b = 0

=====

(c) Equation of line

y = mx + b

y = -3x

Answer:

1/3 is the simplified form for given expression.

Step-by-step explanation:

Given that:

= $\sqrt[-3]{27}$

By simplifying:

Radical sign will be removed as follows:

= $27^{-1/3}$

For removing the "-" sign from power, base will be inverted:

= $(1/27) ^ {1/3}$

27 can also be written as 3 * 3 * 3 = 3^3

So,

= $(1/3^3)^{1/3}$

= $1^{1/3} / 3^{3* 1/3}$

By simplifying we get:

= 1/3

i hope it will help you!

In ΔFGH, f = 960 inches, g = 380 inches and h=820 inches. Find the measure of ∠F to the nearest degree.

WARRIOR [948]

Answer:

$m\angle F\approx 100^{\circ}$

Step-by-step explanation:

For any triangle, the Law of Cosines is given by $c^2=a^2+b^2-2ab\cos C$ , where all three variables are interchangeable.

Therefore, we have:

$f^2=g^2+h^2-2gh\cos F,\\960^2=380^2+820^2-2(380)(820)\cos F,\\\cos F=-\frac{131}{779},\\F=\arccos(-\frac{131}{779})\approx \boxed{100^{\circ}}$
