Find the missing angle measure.

Mathematics
1 answer:
ycow [4]4 years ago
5 0

Step-by-step explanation:

The sum of all inner angles in the shape should be 540°

(180° for triangles, 360° for squares and other simple 4-corner-shapes, the pattern is the number of corners minus 2 multiplied by 180°)

we can calculate

540-106-94-135=205

so we got 205 degrees for the two unclear corners and one of them has to be 5° greater.

x is 100°

x is 100°x+5 is 105°

(note that in the subtraction part we could have subtracted 5 more and would be left with 2x=200)

2) You translate an object point 3 units to the right and 2 units down. Explain (with the aid of an equation) how you would find
uysha [10]

Answer: By adding 2 to y and subtracting x by 3.

Step-by-step explanation: Let’s use the equation y = x since it’s simple. In order to translate an equation anywhere to the right, you have to subtract x by a unit. Since it’s 3 units, the equation is now y = x - 3. To translate an equation down, you have to add a unit to y. Since the questions asks for two units, add 2 to y. The equation should now be y + 2 = x - 3.

Tree casts a shadow 30 feet long. A MHS student standing near the tree casts a shadow 9 feet long. The  student is 6 feet tall. What is the height of the tree? Show all work

<em><u>Answer:</u></em>

Option D

The height of tree is 20 feet tall

<em><u>Solution:</u></em>

From given question,

Shadow of tree = 30 feet

Height of tree = ?

Height of student = 6 feet

Shadow of student = 9 feet

We have to find the height of tree

We can solve the sum by proportion

\frac{\text{height of tree}}{\text{shadow of tree}} = \frac{\text{height of student}}{\text{shadow of tree}}

This forms a proportion and we can solve the sum by cross multiplying

\frac{\text{height of tree}}{30} = \frac{6}{9}\\\\\text{height of tree} = 30 \times \frac{6}{9} = 30 \times \frac{2}{3}\\\\\text{ height of tree } = 10 \times 2 = 20

Thus height of tree is 20 feet tall

A system of two equations is shown below.
Andru [333]
The equations are,
3x + y = 8 ——— 1
4x - 2y = 3 ——— 2

Multiply equation 1 by 2
Which gives,

6x + 2y = 16 ——— 3

Now , add equation 2 and equation 3
Which gives,
10x = 19

From there , x = 19/10
Therefore x = 1.9

Now substitute x = 1.9 in the equation 1

So the equation becomes ,
3*1.9 + y = 8

From that ,
y = 8 - 5.7

Therefore , y = 2.3

So , x = 1.9 and y = 2.3.

Okay?
