The second angle of a triangular kite is four times as large as the first. The third angle is 15 degrees more than the sum of th
frutty [35]
Let's set the first angle as x, the second angle is then 4x, and the third angle is (x+4x)+15, which is 5x+15
the three angles make a sum of 180: x+4x +5x+15=180
10x=165
x=16.5
the second angle is 4x=4*16.5=66

Is (0,0) a solution to 6x - 7y &gt; 20 please include the steps!
leonid [27]

Answer:

No.

Step-by-step explanation:

To determine if (0,0) is a solution to the inequality, substitute 0 for x and 0 for y and check to see. Thus:

6x-7y>20

Substitute 0 for x and 0 for y:

6(0)-7(0)\stackrel{?}{>}20

Multiply:

0-0\stackrel{?}{>}20

Subtract:

0\not>20

So, (0,0) is <em>not</em> a solution.

And we're done!

PLEASE HELP ME. ONLY GOT 10 MINS.
Vikki [24]

Answer:

Step-by-step explanation:

The ratio of the angle is how the angle relates to each other. Let's say that we try to relate Angle A, B, C and get 1 : 3 : 5. That means Angle B is three times Angle A and Angle C is 5 times Angle A

Thus we get the equation:

A

B = 3A

C = 5A

A + B + C = 180, since all the angles of the triangle is equal to 180 degrees

A + 3A + 5A = 180

9A = 180

A = 20 --> B = 3A = 60 --> C = 5A = 100

So Angle A is 20 degrees, Angle B is 60 degrees, and Angle C is 100 degrees.

Hope that helps!
