The answer in 65. A complementary angles are the 2 non right angles in a right triangle, so you have the right angle which is 90 degrees, plus the 2 other angles in the triangle. So 25 + 65 = 90 + 90 = 180.

Tanx cosx = 0
shtirl [24]
You're almost finished.

(sin/cos) times cos = 0

Look at the left side.  You could write it as (sin x cos) / cos = 0
and simply divide numerator and denominator by the cosine (cancel it).

Then what do you have left ? . . .  <u>sin(x) = 0</u>       Do I need to finish this for you ?

An airplane travels 290 km between Austin and Dallas in 1 h 15 min. What is it’s average speed?
aniked [119]

The average speed of the plane between Austin and Dallas is 232 kmph

<u>Solution:</u>

Given that,

Total distance traveled by airplane = 290 km

Time taken for travel between Austin and Dallas = 1 hour 15 minute

Let us convert the time taken to hours

\begin{array}{l}{1 \text { minute }=\frac{1}{60} \text { hours }} \\\\ {15 \text { minutes }=\frac{15}{60}=\frac{1}{4}} \\\\ {\text { 1 hour } 15 \text { minutes }=1 \frac{1}{4} \text { hours }=\frac{1 \times 4+1}{4}=\frac{5}{4} \text { hours }}\end{array}

<em><u>The average speed is given as:</u></em>

\text { Average speed }=\frac{\text { total distance }}{\text { total time taken }}

Plugging in the values, we get,

\text { Average speed }=\frac{290}{\frac{5}{4}}=\frac{290}{5} \times 4=232

Hence the average speed is 232 kmph

a_sh-v [17]

Answer:

Step-by-step explanation:

Y = 1/5 x + 14 where b = 7

Result:

x + 70 = 5 Y

Geometric figure:

line

Alternate forms:

x = 5 Y - 70

x - 5 Y + 70 = 0

Real solution:

Y = x/5 + 14

Solution:

Y = x/5 + 14

Integer solution:

x = 5 n, Y = n + 14, n element Z

Solution for the variable x:
