Mathematics
1 answer:
melomori [17]3 years ago
3 0

Answer:

A= 5/7b +8

Step-by-step explanation:

The basic idea is that you can do anything you want (except divide by

zero) to either side of the equation, so long as you do the same thing

to the other side, too.

What is the estimate of forgive 6in by 4in
NNADVOKAT [17]

Find area of the semi circle.

The diameter is, half of that would be the radius, which is 3.

\frac{\pi \cdot 3^2}{2} = 14.1

Find the area of the rectangle.

6 * 4 =24

Add the two areas together.

24 + 14.1 = 38.1

Please please help ASAP! Classify each angle!
Olenka [21]

Answer:

<h3>             Acute Angles: ∠TLS, ∠SLT, ∠ULR</h3><h3>             Right Angles:   ---------</h3><h3>             Obtuse Angles:  ∠RLT, ∠SLU, ∠ULS,</h3><h3>             Straight Angles:  ∠RLS, ∠TLU </h3><h3>             Not angles: ∠TRL </h3>

Step-by-step explanation:

The lines intersect at point L, so all angles have a vertex (middle letter) L so there is no angle TRL

Straight angle is a line with dot-vertex, so the straight angles are ∠RLS and ∠TLU.

∠TLS is less than 90° then it is acute angle (∠SLT is the same angle). ∠ULR is vertex angle to ∠TLS, so it's also acute angle.

Two angles adding to straight angle mean that they are both right angles or one is acute and the second is obtuse. ∠TLS is acute so ∠RLT is obtuse (they adding to ∠RLS) and ∠SLU is obtuse (they adding to ∠TLU). ∠ULS is the same angle as ∠SLU.

I need help i don’t understand this
lys-0071 [83]
Answer:
Angle BAC: 56
ANGLE BCA: 42

Why? First find angle BCA because that angle is on a straight line with another angle on the other side you can do
180-138=42 which is the measurement of angle BCA.

For angle BAC you have to know that the sun of all triangles interior angles is 180 so you do
180-82-42=56
So angle BAC is 56

Hope this helps :D
