20 points!! please show me how to do this for d + 4 < 7
1 answer:
Step-by-step explanation:
Solve for d, by subtracting 4 from both sides.
To graph the solution, draw a number line, make a hollow circle on 3 and draw an arrow pointing left towards negative numbers. The circle has to be hollow because the solution does not include 3.
To check your work, substitude d for any number less than 3. In this case, let's try with 2.
This is true. 7 is greater than 6.

Answer:
Step-by-step explanation:
The given triangle is a right triangle, meaning it is a triangle with a right angle, this is indicated by the box around one of the angles. When given a right triangle, one can use the right triangle trigonometric ratios. These ratios describe the relationship between an angle in a right triangle, and the sides in a right triangle. Such ratios are as follows,
Bear in mind that the way one names the sides, in the sense of (opposite or adjacent) will change based on the angle one uses to describe the triangle. However, the hypotenuse is the same no matter the angle, as the hypotenuse is the side opposite the right angle.
In this case, one is given one of the angles, and the side opposite the angle. One is asked to find the hypotenuse of the triangle. One can use the sine (sin) ratio to achieve this.
