State the size of angle abd
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.

WebAngle - An angle is formed by two rays with a common endpoint. Angles are measured in degrees (°). Straight Angle = 180° Right angle = 90° Acute Angle > 0° and < 90° Obtuse Angle > 90° and < 180° Angle ABC is a straight angle. Angles ABD and DBC are right angles. Angles CBE and DBE are acute angles. Angle ABE is an obtuse angle. Angles WebMO Z7–I–6 2024. In triangle ABC, point D lies on the AC side and point E on the BC side. The sizes of the angles ABD, BAE, CAE, and CBD are 30°, 60°, 20°, and 30°, respectively. Find the size of the AED angle.
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°
