Answer:

see below

Step-by-step explanation:

5.  sin 31 = opp/ hyp

  sin 31 = 34 /x

x = 34 / sin 31

x =66.0145369

tan 31 = opp /adj

tan 31    = 34/y

y = 34/ tan 31

y= 56.5855024

6.  Pythagorean theorem to find z

9^2+12^2 = z^2

81+144 = z^2

225 = z^2

z =sqrt(225) =15

sin x = opp / hyp

sin x = 9/15

take the inverse sin

x = sin^ -1 (9/15) = 36.86989765

sin y = opp / hyp

sin y = 12/15

take the inverse sin

y = sin^ -1 (12/15) = 53.13010235

Answer:

1. sin(31) = opposite/hypotenuse

sin(31) = 34/x

x = 34/sin(31) = 66.0145369

x = 66.0°

tan(31) = opposite/adjacent

tan(31) = 34/y

y = 34/tan(31) = 56.5855024

y = 56.6°

2. tan(x) = opposite/adjacent

tan(x) = 9/12

x = 36.86989765

x = 36.9°

y = 180 - 90 - x

y = 53.13010235

y = 53.1°

z² = 9² + 12²

z² = 225

z = 15

The expression 1 2 b h 2 1 ​ bhstart fraction, 1, divided by, 2, end fraction, b, h gives the area of a triangle where b bb is t
adoni [48]

Answer:

14cm²

Step-by-step explanation:

Area of a triangle (A) is 1/2bh where;

b is the base of the triangle

h is the height of the triangle

Given the base = 7cm and height = 4cm,

Substituting the given values into the formula of area of a triangle we have;

A = 1/2×7×4

A = 14cm²

Therefore the area of the triangle is 14cm²

Rewrite this equation in Slope Intercept form and
german

Answer:

y = -2x+6

y=8  when x = -1

Step-by-step explanation:

2x + y = 6

Slope intercept form is  y = mx+b where m is the slope and y is the intercept

Solve for y

Subtract 2x from each side

y = -2x+6

The slope is -2 and the y intercept is -6

Let x = -1

y = -2(-1) +6

y = 2+6

y=8

(-1,8)

How do I solve x≤100
Molodets [167]

Answer:


Step-by-step explanation:

There's really nothing to solve here.  Rather, you should describe what x≤100 represents.

To draw an appropriate graph, draw an x-axis, mark x=100 with a black dot, and then draw an arrow to the left from this dot.  That's it.  "All x less than or equal to 100."
