Answer:
45 degrees
Step-by-step explanation:
Here, we want to get the value of the acute angle
From the question, we have it that the sin of the acute angle equals its cosine
Recall;
cos A = sin (90-A)
Hence, if A is 45, then Cos A and Sine A will be the same
This means the value of theta which is the acute angle is 45 degrees
Answer:
3/4
Step-by-step explanation:
2/4 + 1/4
The fractions already have a common denominator
The common denominator is 4
3/4
Answer:
A parallelogram with diagonals that are congruent and opposite sides that are congruent.
Step-by-step explanation:
A square is defined as having all sides equal, and its interior angles all right angles (90°). From this it follows that the opposite sides are also parallel.
-x + 2y = 10
6y = -12x + 1
6y = -12x + 1
6 6
y = -2x + ¹/₆
-x + 2y = 10
-x + 2(-2x + ¹/₆) = 10
-x + 2(-2x) + 2(¹/₆) = 10
-x - 4x + ¹/₃ = 10
-5x + ¹/₃ = 10
- ¹/₃ - ¹/₃
-5x = 9²/₃
-5 -5
x = -1¹⁴/₁₅
y = -2x + ¹/₆
y = -2(-1¹⁴/₁₅) + ¹/₆
y = 3¹³/₁₅ + ¹/₆
y = 4¹/₃₀
(x, y) = (-1¹⁴/₁₅, 4¹/₃₀)
It is intersecting, making the answer equal to C.
