You’re given three angle measurements of 30°, 70°, and 80°. how many triangles can you construct using these measurements?

Sum of all these angle is 180° we can construct one triangle only.

Step-by-step explanation:

Given  : You’re given three angle measurements of 30°, 70°, and 80°.

To find : How many triangles can you construct using these measurements.

Solution : We have given the angle 30°, 70°, and 80°.

By the angle sum property : sum of all angle of a triangle is 180°.

30° +70° + 80°  = 180°.

Therefore, Sum of all these angle is 180° we can construct one triangle only.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°
