Solve the following using the crossing-graphs method. (round your answer to two decimal places.) 5 + 69 × 0.96t = 32

The solution is 22.98.

Step-by-step explanation:

Here, the given equation,

,

Let

And,

Where, t represents x-axis and f(t) represents y-axis,

Since, is an exponential decay function having y-intercept (0,74).

Also, f(t) = 32 is the line, parallel to x-axis,

Thus, after plotting the graph of the above functions,

We found that they are intersecting at (22.984, 32)

Hence, the solution of the given equation = x-coordinate of the intersecting point = 22.984 ≈ 22.98

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
