Line segment L N is tangent to circle O at point M and QM is a diameter.

Oksana_A [137]

Answer:

The measure of ∠QML is 90°

The measure of ∠PMN is 117°

Step-by-step explanation:

In circle O:

MQ is a diameter
LN is a tangent to circle O at point M
PM and RQ are secants
m∠PMO is 27°
m∠MQR is 42

∵ MQ is a diameter of circle O

∵ LN is a tangent to circle O at point M

- A diameter is perpendicular to a tangent at the point of

contact between them (one of end-point of the diameter)

∴ QM ⊥ LN at point M

∴ m∠QML = m∠QMN = 90°

The measure of ∠QML is 90°

∵ m∠PMN = m∠PMO + m∠QMN

∵ m∠PMO = 27° ⇒ given

∵ m∠QMN = 90° ⇒ proved

∴ m∠PMN = 27 + 90

∴ m∠PMN = 117°

The measure of ∠PMN is 117°

Which unit of measure would be appropriate for the volume of a cube with sides of 2 meters

Brrunno [24]

Answer:

The unit of measure appropriate is cubic metre or cubic meter (m³)

Step-by-step explanation:

we know that

The volume of a cube is equal to

$V=b^3$

where b is the length side of the cube

In this problem we have

$b=2\ m$

substitute in the formula of volume

$V=2^3$

$V=8\ m^3$

therefore

The unit of measure appropriate is cubic metre (m³)

Sin 0 = 7/25 and cos 0 = -24/25. Find tan 0

9966 [12]

Answer:

$tan \theta = - \frac{7}{24}$

Step-by-step explanation:

$sin \theta = \frac{7}{25} \ , \ cos\theta = \frac{-24}{25}\\\\tan \theta = \frac{sin\theta}{cos\theta}$

$=\frac{\frac{7}{25}}{\frac{-24}{25}} \\\\=\frac{7}{25} \times \frac{25}{-24}\\\\= - \frac{7}{24}$
