Answer:
Step-by-step explanation:
BD is opposite the 30° angle. The sine of 30° is 0.5. The sin of an angle in a right triangle is opposite/hypotenuse so BD = sin 30°x8.
Now you have two known lengths The third can be found by applying the Pythagorean theorem: BC²+BD²=CD², from which you can establish a numerical value for BC.
1 because you replace x with 2 so, (2)squared -5x2 + 7 = 4 - 10 + 7 = 1
The length is 6 inches and the width is 5 inches
