Answer:

x = -7

Step-by-step explanation:

All triangle angles add up to 180

84 + x + 59 + x + 51 = 180

2x + 194 = 180

2x = 180 - 194

2x = -14

x = -7

the height of the triangle is 4cm and the base width is 18 cm and the base length is 18 cm what is the surface area of a square

Gnesinka [82]

Answer:

The surface area is 664 cm²

Step-by-step explanation:

$A=a^{2} +2a\sqrt{\frac{a^{2}}{4} } +h^{2}$ Use this equation to find the surface area

$A=18^{2} +2(18)\sqrt{\frac{18^{2}}{4} } +4^{2}$ Simplify

$A=324 +36\sqrt{\frac{324}{4} } +16$ Simplify

A = 324 + 36√81 + 16 Simplify

A = 324 + 36(9) + 16 Simplify

A = 324 + 324 + 16 Simplify

A = 664 cm²

slope-intercept form for the line that passes through (-1,-7) and is perpendicular to the graph of 3x+12y=-6

Mrac [35]

Answer:

Step-by-step explanation:

We first need to find the slope of the given line. Putting that standard form of a line into slope intercept:

12y = -3x - 6 so

$y=-\frac{1}{4}x-\frac{1}{2}$

In this form we can easily determine that our slope is -1/4. That means that the perpendicular slope, the opposite reciprocal, is +4. We will write first the point slope of the new line using our given point, then solve it for y, putting it into slope-intercept form. y - (-7) = 4(x - (-1)) and

y + 7 = 4x + 4 so

y = 4x + 4 - 7 so

y = 4x - 3
