Round your answer to the nearest hundredth.
AB=7 AC=4 Angle C=90 degrees Angle A= ?
Answer:
55.15°
Step-by-step explanation:
The hypotenuse and the side adjacent to angle A are given, so the relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(A) = 4/7
The value of angle A can be found using the inverse cosine function:
A = arccos(4/7) ≈ 55.15°

can any one help me??
The molten material before it reaches the surface is called magma.
Before lava reaches the surface, the molten material is referred to as magma. Magma is a mixture of molten rock, dissolved gases, and crystals that is found beneath the Earth's surface within the Earth's crust and upper mantle. It is generated by the melting of solid rock due to high temperatures and/or changes in pressure. Once magma reaches the Earth's surface, it is then called lava. Therefore, the correct answer is b. magma.
