Help me with my math quiz from friday 4/1 <br> SHOW STEPS

Hie!! I will be solving the questions in the sequence of the attachments.

_______________________________________

4. As line SU and TV are intersecting each other at O.

A.T.Q, ∠UOV = (7x - 4)°

∠SOT = 87°

Then, ∠UOV = ∠SOT {Vertically Opposite Angles}

$\rightarrow\sf{7x - 4=87}$

$\rightarrow\sf{7x =87+4}$

$\rightarrow\sf{7x =91}$

$\rightarrow\sf{x =\frac{91}{7}}$

$\rightarrow\boxed{\bf{x =13}}$

_______________________________________

5. radius = 17ft

circumference of circle = 2πr

$\rightarrow\sf{circumference=2\times\frac{22}{7}\times17}$

$\rightarrow\boxed{\bf{circumference=106.8ft}}$

_______________________________________

3. ∠1 and ∠2 - add to 180 (linear pair)

∠1 and ∠3 - equal (Vertically Opposite Angles)

∠3 and ∠4 - add to 180 (linear pair)

∠2 and ∠4 - equal (Vertically Opposite Angles)

_______________________________________

2. 160° + (6x - 16)° = 180° (linear pair)

$\rightarrow\sf{6x - 16 = 180-160}$

$\rightarrow\sf{6x - 16 = 20}$

$\rightarrow\sf{6x = 20+16}$

$\rightarrow\sf{6x =36}$

$\rightarrow\sf{x =\frac{36}{6}}$

$\rightarrow\boxed{\bf{x =6}}$

We have to find horizontal component of Mayosons velocity.

#a

$\\ \tt\bull\leadsto V_x=vsin\theta$

$\\ \tt\bull\leadsto V_x=2.5sin36$

$\\ \tt\bull\leadsto V_x=2.5(0.58)$

$\\ \tt\bull\leadsto V_x=1.45m/s$

Here 2 vectors A=8 and B=2.5

$\\ \tt\bull\leadsto \overrightarrow{R}$

$\\ \tt\bull\leadsto \sqrt{A^2+B^2+2ABcos\Theta}$

$\\ \tt\bull\leadsto \sqrt{8^2+2.5^2+2(8)(2.5)cos36}$

Last semester Jacob spent 1/3 of an hour doing math homework on each evening that he had math homework.he calculated that he spe

Marina CMI [18]

Jacob had math homework on 81 evenings.

Step-by-step explanation:

Time spent of each evening = 1/3 of an hour

Time spent in minutes = $\frac{1}{3}*60 = 20\ minutes$

Total time spent = 27 hours

Total time spent in minutes = 27*60 = 1620 minutes

Let,

x be the number of evenings spent doing math homework.

Time spent each day* Number of evenings = Total time spent

$20x=1620$

Dividing both sides by 20

$\frac{20x}{20}=\frac{1620}{20}\\x=81$

Jacob had math homework on 81 evenings.
