Answer:
C and D give rational numbers, as the square root of 49 is ±7 and the square root of 100 is ±10.
Answer:
y = 68 degrees
Step-by-step explanation:
Here, we want to solve for an equilateral triangle with the internal angle measurement being y-8
If one of the angles is y-8, then the rest are y-8 too
mathematically, by adding all , we have a total of 180
Thus;
3(y-8) = 180
y-8 = 180/3
y-8 = 60
y = 60+8
y = 68 degrees
Answer:
h=13
P=5
b=12
Step-by-step explanation:
- tanA=<em>p</em><em>÷</em><em>b</em><em>=</em><em>5</em><em>÷</em><em>1</em><em>2</em>
- sin<em>A</em><em>=</em><em>p</em><em>÷</em><em>h</em><em>=</em><em>5</em><em>÷</em><em>1</em><em>3</em>
- <em>c</em><em>o</em><em>s</em><em>A</em><em>=</em><em>b</em><em>÷</em><em>h</em><em>=</em><em>1</em><em>2</em><em>÷</em><em>1</em><em>3</em>
