In a triangle abc angle a x b 3x
WebDec 28, 2024 · Let the three angles of the given triangle be A, B and C respectively. So, A = 3x. B = 5x. C = 8x + 4. By the angle sum property of the triangle, A + B + C = 180° 3x + 5x + 8x + 4 = 180° 16x + 4 = 180° 16x = 180° - 4 = 176 . x = 176/16 = 11. Therefore, First angle = x = 11° Second angle = 3x = 3(11) = 33° Third angle = 8x + 4 = 8(11) + 4 ... WebTo solve this problem, we need to use the fact that the sum of the angles in a triangle is 180 degrees. We can set up two equations based on the given information: m²A + m²B + m²C = 180 (Equation 1) m²A = x + 40₁. m²B = 3x - 10 = x + 15 . Substituting the values of m²A and m²B into Equation 1, we get: x + 40₁ + x + 15 + m²C = 180

The measure of angle A is ___°. The measure of angle B is ____ WebIf in triangles ABC and DEF, angle A = angle D, angle B = angle E, and AB = DE, then triangle ABC is congruent to triangle DEF. Proof: This proof was left to reading and was not presented in class. Again, one can make congruent copies of each triangle so that the copies share a side. Then one can see that AC must = DF.
WebMay 30, 2024 · The sum of all angles of a triangle is 180 degrees so we can write an equation as follows. given: m∠A=(3x)°, m∠B=(x+5)°, and m∠C=(x−15)° 3x + (x+5) + (x-15) = 180. 3x +x +x +5 - 15 = 180. 5x - 10 = 180. 5x = 190. x = 38. m∠A=(3x)° = 3(38) o 114 o. m∠B=(x+5)° = (38+5) o = 43 o . m∠C=(x−15)° = (38-15) o = 23 o .
