Answer:
cos B = a/c
tan A = a/b
sin B = b/c.
Step-by-step explanation:
Sin = opposite / hypotenuse
cos = adjacent/ hypotenuse
tan = opposite/adjacent.
Answer:
it's <em>5</em><em>(</em><em>4</em><em>x</em><em>+</em><em>7</em><em>y</em><em>)</em>
Step-by-step explanation:
5×4x+5×7y
20x+35y

Hope it'll help!
X = ?, y = ?;
2 x - 70° = x + 30°
2 x - x = 30° + 70°
x = 100°
x + 30° + 5 y = 180°
130° + 5 y = 180°
5 y = 180° - 130°
5 y = 50°
y = 50° : 5
y = 10°
Answer: C ) x = 100, y = 10
Answer:
x = 3 and y = 2
Step-by-step explanation:
For the triangles to be congruent.
The hypotenuse and a leg of one triangle and the hypotenuse and a corresponding leg of the other triangle must be congruent, that is
x = y + 1 → (1) congruent legs
3y = x + 3 → (2) congruent hypotenuse
Substitute x = y + 1 into (2)
3y = y + 1 + 3, that is
3y = y + 4 ( subtract y from both sides )
2y = 4 ( divide both sides by 2 )
y = 2
Substitute y = 2 into (1)
x = 2 + 1 = 3
