Step-by-step explanation:
given 30°
converting into radian measure
= 30 * π / 180
= π / 6
Step-by-step explanation:
Divide the fraction with 4
Reduce the number with factor 4
Multiply the fractions
Answer:
4/5 is the slope of the line represented by the equation y = 4/5x - 3
This is vague. Any dimensions that make a triangle can make more than one, just draw another right next to it. What's really being asked is which dimensions can make more than one non-congruent triangle.
<span>A. Three angles measuring 75°,45°, and 60°.
That's three angles, and 75+45+60 = 180, so it's a legit triangle. The angles don't determine the sides, so we have whole family of similar triangles with these dimensions. TRUE
<span>B. 3 sides measuring 7, 10, 12?
</span>Three sides determine the triangles size and shape uniquely; FALSE
<em>C. Three angles measuring 40</em></span><span><em>°</em></span><em>, 50°</em><span><em>, and 60°? </em>
40+50+60=150, no such triangle exists. FALSE
<em>D. 3 sides measuring 3,4,and 5</em>
Again, three sides uniquely determine a triangle's size and shape; FALSE

V= pi x r^2 x h
V/(pi x h)=r^2
square root of [V/(pixh)]=r
