-8x - 46 = -6x - 8
-8x + 6x = -8 + 46
-2x = 38
x = -19

The equation:
-8x - 46 = -6x - 8

The solution:
x = -19

The three inside angles (A,B and C) of a right-angled triangle are in the ratio 7:18:11. Th smallest angle is 35. Work out angle

lions [1.4K]

Answer:

<A = 35degrees

<B =90degrees

<C = 55degrees

Step-by-step explanation:

Given the ratios of a triangle as 7:18:11

Total ratio = 7+18+11

Total ratio = 36

Since the smallest angle is 35degrees, hence <A = 35degrees

Get angle B;

<B = 18/36 * 180 (sum of angle in a triangle is 180degrees)

<B = 1/2 * 180

<B = 90degrees

Get angle C;

<C = 11/36 * 180

<C = 11 * 5

<C = 55degrees

Hence the value of A, B and C are 35, 90 and 55 degrees repectively

All exponential functions can be written in many forms. Write the function f(t)=110(1.35)^{\frac{t}{40}}f(t)=110(1.35) 40 t in

Mkey [24]

Step-by-step explanation:

Given - f(t)=110(1.35)^{\frac{t}{40}}

To find - Write the function in the form f(t)=ae^{kt}. Round all coefficients

to four decimal places.

Proof -

Given that , the function is f(t)=110(1.35)^{\frac{t}{40}}

Now,

We can write it in the form of $f(t) = 110(1.35)^{\frac{t}{40} }$

By comparing with the form $f(t) = ae^{kt}$ , we get

a = 110.0000

k = $\frac{1}{40}$ = 0.0250

Please help . In the figure, ∆BAT ≅ ∆CAT. Which statement is not true by CPCTC?

masya89 [10]

Answer:

$\overline{CS}\cong\overline{ST}$

Step-by-step explanation:

The congruence statement for the triangles does not list point (or angle) S, so no claim about segments or angles involving S will be supported by the congruence statement.

The statement

$\Delta BAT\cong\Delta CAT$ tells you ...

$\angle TBA\cong\angle TCA\\\angle BAT\cong\angle CAT\\\angle ATB\cong\angle ATC\\\overline{BA}\cong\overline{CA}\\\overline{AT}\cong\overline{AT}\\\overline{TB}\cong\overline{TC}$

No other claims can be made using CPCTC. The statement among the answer choices that is not true by CPCTC is ...

$\boxed{\overline{CS}\cong\overline{ST}}$
