WebDraw a 30-60-90 triangle and its reflection about the leg opposite the 60° angle. These two 30-60-90 triangles together form a larger triangle. This larger triangle has three 60° angles and is therefore equilateral! The hypotenuse of either one of the 30-60-90 triangles is one of the sides of the equilateral triangle. WebTo find the size of angle ABD, we need to first find the size of angle DEB. Angle DEB is 42* and so its size is 420. Next, we need to find the size of angle ABD. Angle ABD is the angle formed by the lines AB and CD. Since angle ABD is a right angle, its size is 180*.

SOLVED:

WebAn isosceles triangle will have two angles the same size.; In an equilateral triangle, all angles will be 60°.; A right-angled triangle will have one angle that is 90°, which means the other two ... WebNormally, instead of moving the angle, you could actually move the protractor to the angle. So it looks something like that, and you could see that it's pointing to right about the 30 degree mark. So we could say that the measure of angle BAC is equal to 30 degrees.

Web1 Theoretically, if you see $AD$, $BD$, $CD$ as unknown number, then you will obtain the equations $\frac {AD^2+CD^2-AC^2} {2AD\cdot CD}=\cos\angle ADC$ and similarly another two. You have three equations with three unknown number and the equations are of degree $2$. So, at least, THEORETICALLY, you can solve it. – Li Li Apr 24, 2024 at 16:01 Web∠ ABD is a compliment of ∠ DBC because; ∠ ABD + ∠ DBC =90° (right angle). Examples of complementary angles: 40° and 50° 60° and 30° 85° and 5° 70° and 20° 45° and 45° etc. Supplementary angles. ∠ ABD is a supplement of ∠ DBC because; Supplementary angles are pair angles whose sum of degree measurements equals 180 ...

WebAnswer: Solution: (i) In Fig (i), x = y (Angles opposite to equal sides) But x + y + 80° = 180° (Angles of a triangle) ⇒ x + x + 80° = 180° ⇒ 2x = 180° - 80° = 100° ⇒ x = 100°/2 = 50° ∴ y = x = 50° Hence x = 50°, y = 50° (ii) In Fig. (ii), b = 40° (Angles opposite to equal sides) But a + b + 40° = 180° (Angles of a triangle) ⇒ a + 40° + 40° = 180°
