Answer:
Step-by-step explanation:
x represents the hypotenuse of that right triangle. The reference angle is 52 and is opposite AB, the side which we need to find. The trig ratio that uses the hypotenuse and the side opposite the reference angle is the sin ratio, namely:
and
7,7sin52 = AB so
AB = 6.07 m
Answer:
There are no solutions.
<u><em>Step-by-step explanation:</em></u>
Let's solve your equation step-by-step.
−2(3x)+1=7−6x
Step 1: Simplify both sides of the equation.
−2(3x)+1=7−6x
−6x+1=7+−6x
−6x+1=−6x+7
Step 2: Add 6x to both sides.
−6x+1+6x=−6x+7+6x
1=7
Step 3: Subtract 1 from both sides.
1−1=7−1
0=6
Hope this helps.
Daniel made an error in line 3. He wrongly divided the sum of sides and height. The area of the trapezoid is 42 cm².
<h3>What is the area of the trapezoid?</h3>
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides.
Area of a trapezoid = 1/2 x (sum of the lengths of the parallel sides) x height
- Line 1: A = 1/2 x (6) + (7 + 7)
- Line 2: A = 1/2 (6) (14)
- Line 3 : 3 x 14
- Line 4 : A = 42 cm²
