0.4 is four tenths. 0.4 = 4/10=2/5
Gradient =2 because the slope is 2 units. Y-intercept = -2 because it crosses the y-line at -2.
B because the square root of 39 is 6.24499799...
<h3><u>
Answer:</u></h3>
<h3><u>
Step-by-step explanation:</u></h3>
<u>We can clearly see that the triangle is an isosceles triangle. This also means that y must equal to 180 - 115. Let's solve.</u>
- => x + y + 180 - 115 = 180
- => x + y + 65 = 180
<u>Since 180 - 115 equals 65, this means that </u><u>y = 65.</u>
- => x + 65 + 65 = 180
- => x + 130 = 180
- => x = 180 - 130
- => x = 50
<h3><u>Conclusion:</u></h3>
<u>Therefore, our answers are:</u>
