Triangle base is 2.4 what is the height
Fantom [35]

Answer:

Hello!

To answer your question, consider the Pythagorean Theorem- a²+b²=c²

In this case, a would be 2.4/2= 1.2

I cannot answer your question fully because at least two of the three letters should be known in order for the formula to work, as well as to find the height. Was the slant height given?

Ben bowled 121 and 184 in his first two games. What must he bowl in his third game to have an average of at least 170​?
vagabundo [1.1K]

Answer:

205

Step-by-step explanation:

Were gonna start by writing an equation (121+184+x)/3=170 because were adding a 3rd value to the average and x is going to be our value that were looking for. If you solve that, you get 205. Hope this helps.

ABC is a tangent to the circle below. O is the centre of the circle. Work out the size of angle 0. Give reasoning to justify you
Delvig [45]

Answer:

Θ = 46°

Step-by-step explanation:

the angle between a tangent and a radius at the point of contact is 90° , so

∠ ABO = 90°

since OB = OD ( radii of circle ) then Δ BOD is isosceles and

∠ OBD = ∠ ODB = 22°

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ AOB is an exterior angle of the triangle , then

∠ AOB = 22° + 22° = 44°

the sum of the 3 angles in Δ AOB = 180° , then

Θ + 44° + 90° = 180°

Θ + 134° = 180° ( subtract 134° from both sides )

Θ = 46°
