SUPER EASY GEOMETRY PROBLEM, 10 POINTS!!! WILL MARK BRAINLIEST

Mathematics
1 answer:
STatiana [176]3 years ago

75 degrees,
All triangles have a sum 180on the interior angles.
We know 90 and 30,
90+30=120,
180-120= 60.
60 is the measure of angle A.
Angle bisectors “cut an angle in half” per se, so 90/2=45.
45 is the measure of angle ACM
So, 60+45= 105,
180-105=75,
So the measure of the angle in question is 75.

Example of a one-to-one function.
Zanzabum

Answer:

A one-to-one function is a function of which the answers never repeat. For example, the function f(x) = x + 1 is a one-to-one function because it produces a different answer for every input

I really need help with this!

\bf (6n-5)^{\frac{1}{2}}+3=-2\\\\
-----------------------------\\\\
a^{\frac{{ n}}{{ m}}} \implies  \sqrt[{ m}]{a^{ n}} \qquad \qquad
\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}\\\\
-----------------------------\\\\
thus
\\\\\\
(6n-5)^{\frac{1}{2}}+3=-2\implies \sqrt{6n-5}+3=-2\implies \sqrt{6n-5}=-2-3
\\\\\\
\textit{now squaring both sides}
\\\\\\
(\sqrt{6n-5})^2=(-5)^2\implies 6n-5=25\implies 6n=25+5
\\\\\\
n=\cfrac{25+5}{6}

-------------------------------------------------------------------------------------------

\bf \sqrt{y}-7=0\implies \sqrt{y}=7\impliedby \textit{squaring both sides}
\\\\\\
(\sqrt{y})^2=7^2\implies y=7^2

The right rectangular prism will be sliced perpendicular to its base along the dashed line.
Shkiper50 [21]
A] From the diagram given, the gray shape that has been formed by dashed line is rectangular in shape, thus:
The cross section is a rectangle.

b] The area of the cross section will be given by:
A=length*width
length=8 cm
width=6 cm
hence
A=8×6
A=48 cm²

PLEASE HELP ASAP!!!!!!!!
steposvetlana [31]

Answer:

4.6.

Step-by-step explanation:

The rocket hits the ground when h(t) = 0. So

-16t^{2} + 72t + 7 = 0

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = a(x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}

x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}

\bigtriangleup = b^{2} - 4ac

In this question:

-16t^{2} + 72t + 7 = 0

So

a = -16, b = 72, c = 7

Then

\bigtriangleup = 72^{2} - 4*(-16)*7 = 5632

t_{1} = \frac{-72 + \sqrt{5632}}{2*(-16)} = -0.1

t_{2} = \frac{-72 - \sqrt{5632}}{2*(-16)} = 4.6

Time is a positive measure, so the answer is 4.6.
