Find the measure of each angle indicated. Round to the nearest tenth.
Answer:
missing angle = 67.8 degrees
Step-by-step explanation:
[tex]cos-1 = \frac{adjacent}{hypotenuse}[/tex]
[tex]cos-1 = \frac{5.3}{14}[/tex]
[tex]cos-1 = 0.378571428[/tex]
[tex]67.754 = 67.8[/tex]
C) 67.8° is the value of theta in the given right-angled triangle.
What are trigonometric ratios in terms of a right-angle triangle?We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjecen/hypotenuse and
tan = opposite/adjacent.
Given, a right-angled triangle whose adjacent and hypotenuse are 5.3 and 14 respectively.
We know cos(theta) = adjacent/hypotenuse.
∴ theta = cos⁻¹(adjacent/hypotenuse).
theta = cos⁻¹(5.3/14).
theta = cos⁻¹(0.3786).
theta = 67.8°.

Find the angle of the least positive measure (in degrees, not equal to the given measure) that is coterminal with A.
A= -647°
9514 1404 393
Answer:
73°
Step-by-step explanation:
A coterminal angle will be one that is this angle plus some multiple of 360°. We observe that the magnitude of the given value is between 360 and 720, so we can find the coterminal angle of interest by adding 720°.
-647° +720° = 73°
The least positive measure angle coterminal with A is 73°.

Rachel bought 15 packs of colored pencils with four pencils in each pack. She also
bought 32 packs of glitter pencils with two pencils in each pack. Write and evaluate an
expression to find the total number of pencils she bought.
Answer:
124
Step-by-step explanation:
15 x 4=60
32 x 2=64
64+60=124
Rachel bought a total of 124 pencils.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
To find the total number of colored pencils Rachel bought, you can multiply the number of packs she bought by the number of pencils in each pack. Since she bought 15 packs of colored pencils with four pencils in each pack, the expression would be:
15 packs × 4 pencils/pack = 60 pencils
To find the total number of glitter pencils Rachel bought, you can use the same process. Since she bought 32 packs of glitter pencils with two pencils in each pack, the expression would be:
32 packs × 2 pencils/pack = 64 pencils
To find the total number of pencils Rachel bought in total, you would add the number of colored pencils to the number of glitter pencils. The expression would be:
60 pencils + 64 pencils = 124 pencils
Hence, she bought a total of 124 pencils.

what does 10 = 4y equal to
Answer:
Step-by-step explanation:
Simplifying
10 = 4y
Solving
10 = 4y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-4y' to each side of the equation.
10 + -4y = 4y + -4y
Combine like terms: 4y + -4y = 0
10 + -4y = 0
Add '-10' to each side of the equation.
10 + -10 + -4y = 0 + -10
Combine like terms: 10 + -10 = 0
0 + -4y = 0 + -10
-4y = 0 + -10
Combine like terms: 0 + -10 = -10
-4y = -10
Divide each side by '-4'.
y = 2.5
Simplifying
y = 2.5
