UNO [17]3 years ago
7 0

Answer:

1. z=140

2. z=130

3. z=145

4. z=180

5. z=155

6. z=120

Step-by-step explanation:

1. z+40=180 so you should subtract 40 from both sides of the equation to get 180-40=140, meaning that z=140

2. 50+z=180 so you should subtract 50 from both sides of the equation to get 180-50=130, meaning that z=130

3. subtract 35 from both sides of the equation to get 180-35=145, meaning that z=145

4. You can just solve this equation as 90+90=180, meaning that z=180

5. subtract 25 from both sides of the equation to get 180-25=155, meaning that z=155

6. subtract 60 from both sides of the equation to get 180-60=120, meaning that z=120

The two lines shown intersect at the point (a,b). Find ab. Each unit square in the grid represents a distance of 1.
Ket [755]

Answer:

(9/5, 8/5)

Step-by-step explanation:

First you want to find the equations of the lines. One line is y = 2x - 2 and the other line is y = 1/3x + 1. Then you want to find the x and y that both work in the two equations.

y = 2x - 2

y = 1/3x + 1

Then you do 2x - 2 = 1/3x + 1

Then you do some maths and you get 9/5, and 8/5

ΔMNO is shown.
JulijaS [17]

Answer:

ABC - AAS

DEF - not enough information

GHI - not enough information

JKL - SAS

Step-by-step explanation:

SAS postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.

AAS postulate states that if two angles and the non-included side one triangle are congruent to two angles and the non-included side of another triangle, then these two triangles are congruent.

HL postulate states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.

ASA postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

SSS postulate states that if three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.

1. In triangles MNO and ABC, there are two congruent sides and non-included angle - AAS

2. In triangles MNO and DEF, there are two congruent sides  - there is not enough information

3. In triangles MNO and GHI, there are three congruent angles  - there is not enough information

4. In triangles MNO and JKL, there are two congruent sides and included angle - SAS

The first three terms of a sequence are given. Round to the nearest thousandth (if
tangare [24]

The 7th term of the sequence to the nearest thousandth is 223.949

<h3>What are geometric sequences?</h3>

These are sequence that increases in an exponential form.

The formula for calculating the nth term of a geometric sequence is expressed as:

Tn = ar^n-1

Given the following parameters

a = 75

r = 1.2

n = 7

Substitute the given parameter into the formula

T7 = 75(1.2)^6
T7 = 223.949

Hence the 7th term of the sequence to the nearest thousandth is 223.949
