The measure of the largest angle of the triangular patch of grass is 81 degrees

<h3>Application of sine rule</h3>

In order to determine the measure of the largest angle, we will use the expression below;

\frac{60}{sin26^0} =\frac{135}{sinx^0}

Cross multiply

135sin26 = 60sinx

sinx = 135sin26/60

sinx = 59.18/60
sinx = 0.986

x = 80.5 degrees

Hence the measure of the largest angle of the triangular patch of grass is 81 degrees

VladimirAG [237]

Answer:

The tower is about 235 m.

Step-by-step explanation:

Let x be the height of the tower

tan θ = opp / adj

tan 78 °= x / 50

x = 50 tan 78 °

x = 235

∴ The tower is about 235 m.

2. Write the slope-intercept form of the equation for each graph described. Line passing through (-5, 12) and parallel to the li
Nostrana [21]

Answer:   y = 2x+22

========================================================

Explanation:

The equation y = 2x+5 is in the form y = mx+b

m = 2 = slope

b = 5 = y intercept

Parallel lines have equal slopes, but different y intercepts. So the answer will be in the form y = 2x+c, where b and c are different numbers. Since b = 5, this means c must be some other number. If c = 5, then we'd have the exact same line.

Let's plug in (x,y) = (-5,12), along with the slope m = 2, and solve for c

y = mx+c

12 = 2(-5)+c

12 = -10+c

12+10 = c

22 = c

c = 22

Since m = 2 and c = 22, we go from y = mx+c to y = 2x+22

The equation of the parallel line is y = 2x+22

The graph is below.
