Answer:
Step-by-step explanation:
The diagonals of a rhombus are perpendicular to each other, so angles (2) and (3) are equal 90°.
To find angle (1), we can use the sum of internal angles in the left triangle with angles 52°, (1), and (2):
The diagonals of a rhombus bisects the angles, to the angle next to the angle of 52° is also 52°, then, in the upper triangle, we have:
it might be quantity btw I love your pfp
Step-by-step explanation:
3(x2+2x-3)-4(4x2-7x+5)
3x2 + 6x - 9 - 16x2 + 28x - 20
-13x2 + 34x - 29
